To not provide DSS with a room

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.

Yes, he really is. He wants the best for his older son

But he wants you to contribute half like you don’t do all the caring for the baby and care for the baby like you don’t work. You’re not actually financially supported. I would 100% not let the friend do the work, no one wants shoddy work on their house. Out of interest what will he be paying when it’s your house? And when does he step up around the house?

heroinechic · 29/06/2025 00:03

If he proposed moving into a home where your child didn’t have a bedroom, would you leave him? I would.

Itsrainingloadshere · 29/06/2025 00:03

If he had managed his money properly he wouldn’t be trying to squeeze into your house.

He’s a grown man and seems to be taking advantage of you, you shouldn’t be paying 50% of things if you earn less, and now because he’s wasted all his money he’s trying to cocklodge with you and push your daughter out of her room.

Maybe suggest he rents nearby with his son while he cuts some of his costs eg the car, and he can save for a deposit on a joint house.

Don’t let him pay for work on your house as it can lead to him having a claim on some of its value. I’ve already commented re building regs, it’s a massive job to convert a garage properly to get approval.

It’s clear that you’re putting your daughter first and that’s lovely.

Codlingmoths · 29/06/2025 00:06

I just think I’d have the ick from his lack of baby care. ‘No I’m not that invested in having your son live here, I see you prioritise him and I feel sad that you can’t be arsed caring for your baby, apparently that’s my job. So my priority has to be to cherish the child who’s mine and who’s also less loved and drastically less cared for by her dad. Converting the garage would be 1000x the effort you’ve ever put into your baby you don’t even pay for them really. How about you take baby, cook them some dinner and feed them, while I go for a walk, and think about what kind of dad you really are? To BOTH your children.’

MrsdMrsIMrsffi · 29/06/2025 00:07
  1. It’s wrong you pay half each to the bills- he should pay more as he earns more split like 75/25%
  1. You are right to give your dd her own room back- do not change this.
  1. Shoddy work will devalue your house so don’t go for that- you own it so your rules.
  1. You can sort the garage by leaving a front area of the garage near the door for a small storage area so the nice garage door stays on the outside, then a wall is built up a few feet in from the garage door to separate the front storage from the bedroom. If it’s being built up you can make the space work with high sleeper bed/ storage.
  1. You would be unfair I think, to say DSS cannot stay. Is there nowhere else that could be set up for him? How old is he? Would he be better sharing with the baby if it’s short term?
  1. Be wise it’s your home and if he lives there does he get more say in it legally or it becomes partly his.
SueblueNZ · 29/06/2025 00:08

With an adjustment, could this house be your long(er)-term home? If you are truly only intending to be in the house for a year before selling it, I think he needs to accept that in the interim his son has the small room. But that is a long time for your baby to be in your room; could baby share the second bedroom with your daughter?
Is it an internal garage with a door into the house? If so, what conversion is necessary. Could you simply carpet the floor, cosy up the walls with curtains or gib board or ... install some heating and make it into a bedroom for the son? I would definitely not remove the garage door and permanently remove the 'garage' function for the next owner.
If the quick/cheap fix option is not possible for the garage, are there other options your partner could TAKE A LOAN TO PAY FOR. In this case, the cost of the renovation - such as a room in the garden, or (big cost!) attic room - would need to be ring-fenced to him so that the cost is owed to him in the event you separate.
As others have said do not allow him to pay the mortgage - but he should pay you rent or have the equivalent amount offset against what you contribute to household finances.

You are deluded. Stop making excuses for him.

The 50% bills thing is an issue, but I have some spousal support from exH and I’ve been getting a rental income from my property, so although I earn a lot less, we have a similar income coming in.

However, due to my shorter working hours I do all of the care of our baby son, and 90% of the housework and cooking. Until I put my foot down recently I was also running around like a blue arsed fly doing two separate school runs a day so that I could collect his son, then making tea and providing childcare until he got back from work. So he really does get a good deal for 50% of the bills.

Does the rental income just cover the mortgage on the property or does it leave you some residual income as well? If so, your income after expenses will be a lot less going forward and the bills split will be an ongoing issue. And yes, he does seem to be on a very good deal. Is he actually aware of this, or does he take it for granted?

Tiswa · 29/06/2025 00:17

So the only thing he insists on being equal is financial

do not let him renovate your house it gives him a claim

I rhink living separately is necessary for your daughter and to work out exactly how it will be equitable going forward for everything

InWithPeaceOutWithStress · 29/06/2025 00:18

Sounds like he needs to rent a 2 bed for him and his son whilst you all wait for your house to sell and you can purchase your 4 bed. It’s not ideal but it is what it is.

MsOvary · 29/06/2025 00:18

What are you getting from this relationship. He seems to be taking the piss financially atm - do you see this changing anytime? I think I’d just live on my own with the kids and do what he initially proposed whereby he stays with you when he has not got his son.
you need to protect your assets - I’d be very reluctant to take on a financial committee with this man when he seems to be useless with money.

SleepingStandingUp · 29/06/2025 00:19

I'd agree to convert the garage, assuming it will be warm enough but the door stays. You're looking at selling short term so you'll devalue the house if you mess to much with the garage. If the garage door is an issue appearance wise, could you look at some sort of false wall? But he needs to be paying for it all. Take photos of the garage now so that when you sell it you have photos of it as a garage and convert it back at the last moment

I had a large deposit so it’s small mortgage £600 that I can easily pay myself. The rental income paid this and gave me an extra £1000, but the rental on our larger property is so high that my half swallows any rental profit up. I won’t be any worse off moving back

SpryCat · 29/06/2025 00:26

You are frustrated with him because he has spunked his money and can’t put down any deposit on a mortgage for a larger house. He will have to live elsewhere to accommodate his son because your house is too small and he hasn’t got the money to put down a deposit in order to buy a larger house.
He is hopeless with money, You can’t change him and you will be living apart until he saves up or he doesn’t and you stay living apart.

Rainbowqueeen · 29/06/2025 00:28

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.

Lookuptotheskies · 29/06/2025 00:31

I'd suggest he has a small house or flat with his ds while you spend the time doing up your house to sell.

Propose you both save during this time, spend as much time together as you all can, and reassess as you go.

I'd not want him to move in in these circumstances and as you say he likely won't want to either.

I think an interim time period where you each have separate addresses is the only way to go really!

4forksache · 29/06/2025 00:42

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.

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.

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.

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.

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.

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.
