To not provide DSS with a room

594 replies

Moorside111 · 28/06/2025 22:30

Currently living in rented accommodation with partner, our baby, my daughter from ex marriage and his son from his ex marriage. Both step children are 50/50 with their other parents. We currently live in a large house with lots of space and a bedroom for everyone. But the cost of this rent and associated bills is astronomical and we need to either buy our own 4 bed house or rent somewhere cheaper.

My partner earns double what I earn and works long hours. I have a less demanding job and so do most of the housework and childcare for our baby. This might sound ok- apart from the fact that we pay half each of the rent and bills for our current home. So I really feel like he’s onto a pretty good deal. I used to do childcare and school runs for DSS too and recently stopped….but that is another story.

I own a three bed semi, bought with the proceeds of my divorce, which I lived in with my daughter before I met my partner. It’s a lovely house which I renovated and is in a nice desirable area. It’s been rented out but the tenants have given notice to leave in August.

My partner sold his marital home, gave his ex wife 2/3 of the equity and has since burnt through the rest of the money. He has nothing for a deposit for a new home and so we need to sell mine, which would give us a decent deposit for a new 4 bed house.

Ive decided that I don’t want to move to another cheaper rented property, they’re rarely decorated nicely, don’t feel like home to me and I’d probably have to live in a less nice area to get the size we’d want for a cheaper price. So I’ve decided to move back into my 3 bed semi, spruce it up a little bit and eventually sell it- I’m estimating this might take 12 months or so. My daughter loves this house, it’s near school, friends and her dad. She’s looking forward to going back to her old room. When I initially told my partner that I thought this was the best idea, I discussed it with a view to us all moving there together- it would be cramped and not ideal- but it’s a home and only a stepping stone to us buying somewhere bigger. I suggested we put our 1yo baby in with us and decorate the 3rd bedroom for his son. He didn’t like this idea, said I wouldn’t put my daughter in the small room so why should he put his son. He said he’d rent a house so that his son could have more room and when his son was at his mums he would stay with me and our baby.
He suggested that his son and our baby could have the second double room and my daughter have the small room. This might be where I’m being selfish as I won’t compromise on my daughter- the room was hers to begin with, I don’t want her impacted by my choice to blend a family. She was happy to move in with partner and son btw and they all get on well so there’s no issues there. But I also selfishly don’t see why I should impact my daughter for someone else’s child.

We left it like this until this week where he’s realised the move is imminent and he’s now decided he wants to move to the three bed house with me. He said he doesn’t want to live apart from me and our baby- and I don’t want to live apart either. However, I’ve now planned to have a bedroom for each of my children. I going back to work this week, our 1yo is starting nursery, he’s a light sleeper and for the sake of both of us I think he needs his own room for a good nights sleep instead of us waking each other up in a shared room.

my partner has now decided he’ll convert the integral garage for his son so that he’ll have plenty of space. I initially said this would be ok but I’m now feeling uneasy about this too. He’s planning on doing this renovation himself. I didn’t think much damage could be done until he said he was planning on taking the garage door out and getting our friend to fit in some french doors so it would look more like a room. I have two issues with this:

1- friend has done work for me before and it’s shoddy. I worry what the finish of this DIY project will be.

2- the garage door was only put in a couple of years ago, it was expensive, it’s remote electric and matches the front door. The garage was newly rendered and it all looks smart from the road.

AIBU to say no to this project? It feels selfish and I’m basically saying I won’t allow a room to be made for DSS. Creating the room allows us to stay together and still have DSS over to stay. Surely lots of people would do anything to keep the whole family together.

i feel selfish, but also a bit angry that everything has fallen to me- childcare, bills, providing a home. Now I’m potentially damaging my home, my only asset, so that I can house his son.

I realise the phrase ‘his son’ sounds horrid from a step mum and it’s not a reflection of how I am at home. I care for him, treat him the same as my daughter and son. But in reality he has a mother and father- and it feels like his father’s job to ensure he has a house big enough for his family.

  1. He earns more but has fuck all…
  2. He’s dictating how things are going to be in YOUR place?…
  3. He’s insisting on his shoddy work trade mate in YOUR place

This guy is not a partner. He’s a dictator and he’s not a good bet. I’d let him move out and lose his number.

Moorside111 · 28/06/2025 23:03

I had no idea about regulations, but I’ll discuss this with him and this on its own might be the end of the idea

Yes, building regs are important as you will need everything to be signed off by them because otherwise you will encounter all sorts of problems if/when you want to sell. You will need to pay for building regs, so I suggest you start by giving them a call. Also, the electrics need to be certified by a Part P installer, so you will need to use a fully qualified electrician. I have just had a downstairs toilet installed in my cupboard under the stairs, and I found the building regs people to be extremely helpful. The conversion is definitely not as simple as your DP implies.

Moorside111 · 28/06/2025 23:07

We haven’t had a discussion about what he would pay towards my mortgage and bills. He only brought up the idea of moving into the house today

If he pays towards your mortgage, he will have a financial interest in your house. I do not think he is the man you think he is. I also think you should live apart and I think the scales will start to fall from your eyes.

Codlingmoths · 29/06/2025 03:52

Cassieskinsismad · 29/06/2025 03:40

OP stop giving away all your power. You don't discuss the need for building regs with your partner and hope he changes his mind about the conversion. You TELL him it's a no. It's your house, you have final say in decisions.

You're not married to this guy. There is no "we" or "us" when it comes to the house. It's your house! You mustn't let him pay for anything except giving you money towards bills and food. And obviously contributing towards his baby's costs. And paying all his child's costs when his son is there. No bills in his name, no payment towards the mortgage, no paying for decorations or renovations. These things potentially give him a legal claim on your home if you split up.

He's a "great partner" except you're financially incompatible... that's a huge incompatibility OP. You've been saving for your future, he's been spending, knowing you'll step in to take up the slack. It's so disrespectful. You'll have a bigger mortgage now than you needed to, if you buy a joint house with him. Since you're paying half, that's more interest payments for you OP. Why buy a house with someone who's just shown you such disrespect?

The bullshit about you doing all childcare and housework because you earn less is also disrespectful. As if by earning less you're somehow working less hard than him. It's also taking the piss for him to have this attitude whilst you're still paying half the bills! It doesn't matter how much you earn when you're paying half anyway! I'll bet you're paying more than half too, because you're probably paying for everything that your children need as well. He's done some fancy footwork (mind games) getting you to believe it's fair and accept it, OP.

I wouldn't have him move in at all. He's tried to manipulate you into giving the bigger room to his children. When the threat of living separately didn't work to get his own way (and it was just an empty threat, since he's made no attempts to secure a flat for him and DSS), he's backtracking and announced he's moving in! Erm, no. Since when is it ok to just decide you're moving into someone else's house?! Also announced he's going to do renovations on someone else's house using his bodgy mate. Nobody who is a decent person behaves in these ways. Nobody. He's displayed lack of interest in, or consideration for, the value of your asset (your house) or your wishes in the matter.

It's extreme cheeky fuckery to even ask nicely if he can renovate someone else's house, let alone speak about it as if he automatically expects it to happen. He's not the nice man you think he is OP. He's only nice when he's getting what he wants. The manipulation attempt over the room is an indication of his tendencies when he doesn't get his own way. And the cheeky fuckery around moving in/renovating is mind blowing entitlement and breathtaking arrogance.

He doesn't see you two as a team. If he did, he wouldn't have spent his house deposit money, he'd have took some of his wages and added to his savings not depleted them. He sees you as someone he can use, a cash cow to milk, someone to provide him with the lifestyle he wants and can't afford alone.

The minute you own a shared house with him ie the minute you're trapped, it's going to get worse and whenever you don't acquiesce to his wishes it'll be "if you don't like it you know where the door is" and he'll make your life hell by doing whatever he wants and leaving everything housework and childcare to you. Apart from splitting up and forcing the sale of the house, there won't be a thing you can do about it. You're already resentful. The baby showed up the cracks in your relationship which you previously couldn't see and those cracks are still growing bigger. They're not going to get smaller by buying a shared house. Don't do it to yourself.

Agree totally except he can pay rent. Op just needs to make sure it’s labelled rent and is at or below market reasonable.

Do not sell your house to buy you all a bigger one when he has burned through his money!!!

☝🏻
also think you should stay living separately with your children and let him provide for himself and his child
I can’t readily see what he adds to your life - stress 🤔

ttcat37 · 29/06/2025 03:35

What did he do with the rest of the equity from selling his house?
Where is he going to magic up the £££££ to convert the garage? If he has a 5 figure sum to do that, why can’t he put that towards a house deposit? I would not be letting him, as someone you’re not married to, make big changes like that to property only you own in case he could make some sort of claim on it should you split.

Where did you find this prince, and if you’ve had a baby together why on earth aren’t your finances properly combined, ie why are you paying half the bills when he earns more??

Also how did he burn through all this money??

I’d rethink the whole thing if I were you, however it would be crappy not to convert the garage for his son to have a room, given he lives with you 50% of the time. Just tell the prince he needs to take out a loan and do it properly.

I can see it’s annoying, but the chaos of the adults around him is not your stepsons fault, whereas you have chosen this situation, so you gotta put your back into it, or get shot of Mr Useless.

Financial differences are the major reason for relationship breakdowns. This man and you clearly have very different financial values.

Id suggest he rents on his own and sorts his finances out. I can’t imagine wasting away my share of the family home after a divorce when I had a child to house. That is just insane. He clearly earns well. What is he doing with his money? There is no way I would ever tie myself to him financially.

It’s not just financial differences though- he’s not only stingy but obviously a very lazy parent too- he’s had the op running after his son and doing all the pick ups and tea times until very recently, and now he still only has to pick up his older son and the op does everything for their baby. I think he should live somewhere else with his son, where he isn’t facilitated and nothing gets cooked or cleaned unless he’s done it and got his son to do it, and take his baby for contact where he also has to do 100% of the care for his contact time, and be an actual parent. Parenthood is not optional just because you found a woman to live with. Chuck him out op, tell him you can reconsider in a year if he’s done lots of actual parenting and cooking and cleaning in that year and wants to come back as someone who pulls his weight, a real dad and partner.

Chickensky · 29/06/2025 02:49

"together so that we can jointly buy a home for us all. And now he’s asking to make changes to my smaller house to get around this"

Reason being he spent his previous equity...be careful OP. Don't sell, borrow or lose your own hard won gains.

AcrossthePond55 · 29/06/2025 02:45

@Moorside111

I just don't feel he's all that 'desirable' as a husband and certainly not as someone I'd want to 'tangle up' my finances or buy a house with. As a partner, it's different. With a partner you can end the relationship and walk away with your finances intact as long as you set things up right. Not so in a marriage where 'marital assets' come into play.

He wants to buy a house together but hasn't made it a priority to save up the necessary. He blew through his divorce settlement rather that set it aside to buy something for himself and his son, or at least as a rainy day fund. Now he wants you to subsidize the purchase of a joint house by selling your most valuable asset, your main security, and investing that money in something he will have a financial interest in. No way. Not just no, but hell no!

And you doing the lion's share of the 'home duties' but paying half of everything? I'm not even going to get into that because it just makes me so angry.

My suggestion is that he and DSS rent somewhere. You and your two move into your house. And once the dust has settled on the moves, you stop and consider how nice your house is. Then consider how much less you're having to do in home duties. And I'll bet you have a bit more money left at the end of the month, too.

LardoBurrows · 29/06/2025 02:26

This bloke is using you financially and domestically. He lets you pay 50% of everything and do all of the domestic chores and childcare despite being on a much higher salary. Where is your self respect and anger at being used?

If it were me I'd be telling him that the garage stays as is, especially as you and he haven't got the first idea about building regs. He needs to rent a small flat for him and his son and he needs to sort this out himself, not get you to do it for him. The only reason he hasn't done this is because he has suddenly realised that you won't be there to subsidise him and provide free childcare and housekeeping. You are being taken for a mug, find your backbone and tell him no more. He needs to provide for his son himself and to start saving for a deposit if he wants to buy a house with you.

outerspacepotato · 29/06/2025 02:10

"This lady needs legal advice and protections before she lets any bloke start faffing around with her separately owned property."

This, this, this.

Please get legal advice before you let him or a buddy of his touch anything. If I understand your laws correctly, him doing diy and investing time and money into your own home could give him a claim to a portion of the proceeds when you sell or if you split up, owe him money.

This is your child's security and your baby's and yours. You need to wise up and tell this dude no, he's not messing with your biggest asset.

It sounds like you're afraid to tell him no over his fucky diy plan. What are you afraid of here?

He's got more salary than you. He can house his kid and himself.

RawBloomers · 29/06/2025 01:58

I realise you’re asking about holding firm on your temporary move back to your home but I think you need to look at the longer term as well.

How has he burnt through his third of the divorce settlement? And this with you taking on the expense of cooking/houskeeping and childcare. He should have brought up the need to cut expenses and put the kibosh on having another child (assuming that was planned).

Was there a temporary reason that wiped out his capital or has he just been living beyond his means? What would he be doing going forward now he no longer has that capital? Was he expecting you to pick up the extra somehow?

I think you need to challenge him to sort his finances and attitude to money out. I would be worried, in your position, getting more financially involved with him. Even if you protect your housing deposit, you could end up in a position where you find yourself subsidising him again.

Would you all moving back to your house, converting the garage legally, and staying there instead of selling be on the cards? With him paying rent (with legal advice so he doesn’t get a claim on your house) and 50% of living costs and you keeping your finances entirely separate?

Just stay in your 3bed. Interest rates and selling is hideous right now. You have a nice property ideal for your daughter that she loves and is comfortable in. A good school zone can be hard to get!

I would prefer a 3 bed with garage to a 4 bed with no garage and most people are the same so I’d absolutely refuse the garage conversion.

Would an extension on the back work? I’d let DP pay for these costs! He earns double you and is contributing the same, so he has extra savings! Your baby shouldn’t be costing you more to raise!! Stepson will benefit from being in a good school district too. In the short term can a nice sofa bed be put anywhere?

DP giving his ex 2/3rds and then blowing the rest isn’t your issue. Don’t marry this man either!

The fact you are telling her not to marry this man should really inform all the other advice you are giving: any man she shouldn't be marrying should also be a man she shouldn't be living with!! And certainly he shouldn't be someone she is altering her home for!!
The problem with allowing him to pay for any alterations to her house is that he'll want that money back - and will fight for it - if and when (seems more like when) the relationship breaks down. And if she doesn't have the money to pay him then she will have to sell the house. Which would be a dismal situation.

She should not allow any work to be done on her house unless she is 100% the person paying for it and it's all being done because she wants it to be done. Anything that starts to muddle the waters on who owns and maintains that property is just asking for trouble down the road.

Seems to me that if these two didn't have a child together most of us would be telling her to ditch him and that she could do far far far better. Including just being by herself and living in her lovely home with her daughter. Plus that home has a perfect room already for 50/50 custody with her baby.

MischkasMum · 29/06/2025 01:32

Unreasonable? I think not. Why the holy HELL are YOU paying for all this stuff when he earns double the amount you do? What is he doing with his money? Why can't he pay to have this renovation job done properly, especially if it cost you so much initially? Hate to say it but your partner appears to know where he's getting his bread well-buttered - basically having his cake and eating it too. Time for the order of the boot!

I’d let him convert the garage- professionally but maintain the garage door at the front. Put in a side window if necessary. Do it in such a way that it can easily be converted back to a garage if necessary.
Definitely no French doors. A window with bricks under, at the very most of he really insists.

I wouldn't let him touch the house at all - it's her own separate property. The more he starts doing work on it the more likely there will be financial drama in the future if the relationship doesn't work out and he claims he's owed money for what he will argue is increased value to the house. Also remember that even garages that are part of the property often aren't built with appropriate insulation - and crappy conversions can lower the value of a home rather than improving it. Not great if they end up splitting up (which seems likely given they are already on totally different pages as far as finances and children are concerned) and she not only has to pay to have the crappy conversion removed, but also has to pay him for any value he claims to have added to the property.

This lady needs legal advice and protections before she lets any bloke start faffing around with her separately owned property.

outerspacepotato · 29/06/2025 01:28

You're being suckered financially by a guy who gave his ex wife 2/3 of their home equity and has squandered the rest.

He earns more but has you carrying more than your share of the financial load.

Do not let him and his friend do a shit diy to your biggest asset. That's taking money out of your pocket.

In your situation, I would move back to your home with your kids and he would have to find a place. He's already taken financial advantage of you and is going to fuck you over financially big time. Like life altering big time.

Caligirl80 · 29/06/2025 01:28

There's a lot about how you are describing this situation that makes me (and I suspect a lot of other people) wonder whether this is actually the man for you. You've described a lot of problems that are fundamental - and aren't going to get better:

  1. He has "blown through" a lot of money rather than saving it and trying to square away a similar option for a purchased house for you both.
  2. He wants to live in your own separately owned home, but doesn't respect the fact your daughter already has her own room there.
  3. He wants to make changes to your own separately owned property, but these are ones that will lower the value of the property and do not address the fundamental issue which is that you are already arguing about which child should live where.

Sounds like you are moving waaaaay too fast in this relationship and need to slow things down immensely. I would urge you to consider that it will be better in the long term for you and your daughter to move back into your own separately owned home, and for your boyfriend to square away his own living arrangements for himself and his son. You can then have custody 50/50 of the baby and can visit with each other until he's squared away enough money to be on an equal footing as you in terms of contributing to a jointly owned home. If the idea of selling your home and buying one jointly with him gives you the fear or worries then you've answered your own question in terms of whether this man is the right one for you. Sadly, relationships where there are fundamental disagreements about money and different approaches to money and savings are rarely successful.

As for your comment about him earning more and therefore needing to contribute more to rent etc: if you guys were married then anything earned during marriage would be a 50/50 split anyway - so you may need to adjust your thoughts on how finances are split during marriage - as far as the law is concerned you put it all in together.

Whatever happens: Get legal advice on how to make sure that your separately owned home remains your own personal separate property. Do NOT allow him to spend any of his money or time making changes or "improvements" to it - because down the line he may well argue that he is owed that money back. Do not add him to any kind of ownership paperwork, and do not allow him to pay for any mortgage payments or anything like that. You owe it to your daughter and other child to make sure that they have the benefit of that house whether you stay with this guy or not.

Please get yourself a therapist so you have some to examine all of this with. Could it be that you are co-dependant and have issues living by yourself? Could it be that you think you think you need a bloke around to be happy? That and child care is no reason to be living with a man who isn't right for you.

Obeseandashamed · 29/06/2025 01:14

This man is taking advantage. I usually hate LTB advice but he’s really selfish and it’s very obvious.

Seventree · 29/06/2025 00:57

Your DSS deserves to be treated completely equally to his step and half siblings.

If you and his dad can't work together to treat all the children in the family fairly, you shouldn't be together.

healthybychristmas · 29/06/2025 00:45

Time and again he's shown you how selfish he is. I'd move back with my kids and without him.
