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.

You’ll need deeper foundations to load bear the weight of a proper converted garage room. Also, removing the garage door requires the new foundations, in order to transfer the load to the ground.
You can’t just get your partner’s shoddy mate to do a crap job. Imagine when you come to sell the house and it doesn’t pass building regs!

Think you need to protect your home and work out if step DS could share with your partner when he’s at yours?

So you and DD in her old room.
DP and his son in second double.
Baby in small room.

As others have said you will need to meet Building Regulations standards if the garage is converted and it will need to be officially signed off by the inspector.

if you convert and don’t get the sign off you are likely to have trouble selling it as most people won’t touch a property where there’s been work done with no Building Regs sign off.

And people want garages. Losing the garage isn’t a selling point.

Meadowfinch · 28/06/2025 23:38

Redpeach · 28/06/2025 22:55

A matching garage door is more important than making an extra bedroom for his son?

The value of and saleability of OP's house is more important than housing the son of someone who does not pay his way.

Genevieva · 28/06/2025 23:39

Your partner might earn well, but he can’t afford to provide a house for his family because he’s burnt through the proceeds of the sale of his old house. If he’d kept that third intact, you could sell your house now, combine the cash and buy something bigger. You can’t, so he’s going to have to suck up the consequences. If he is living with you he will need to pay you rent. Do not allow a budge job man to alter your garage. However, if you think it would end or you to stay in the house snd not sell, get a proper builder to do the work nicely.

Stripeyanddotty · 28/06/2025 23:40

On the upside at least @Moorside111 knows how her dp operates so if they split and he gets another partner she has an idea of how her son will be treated.

SpryCat · 28/06/2025 23:41

You can’t afford to rent the four bed house as it’s so expensive, you have your own house, that you’ve rented out but the tenants are moving out soon. He had money from the sale of his marital home but has blown it, but he expects either your daughter to move back to a smaller bedroom, even though the bigger one has always been her room in the past or he bodges up the garage! Can you not see he wants to deliberately upset your DD so his son gets the biggest room in Your house or he wants to devalue Your house by doing a bodge job on the garage! All these impact either your child or the value of your house. Add in that you are doing all the childcare and cleaning etc it’s extremely one sided with no effort on his part.

Stripeyanddotty · 28/06/2025 23:42

Never mind the fact that her daughter by her previous relationship is being screwed over by her current partner.

Dweetfidilove · 28/06/2025 23:43

There's so much wrong in this relationship that my only advice is to move in with your two children and the rest.

Lord only knows what else you can expect from this monumental fuckup except grief and possible financial ruin.

Namerequired · 28/06/2025 23:44

Why is he paying maintenance if he has 50/50 residency? Why are you doing childcare, housecare and paying 50/50 bills when he earns double?
If you put the deposit down on a new house then make that a percentage of the house you own. If you just protect your deposit amount it will make nothing and actually go down in worth surely.
If he had moved in with you to your house at the start would he have asked you to move your daughter out of her room? He still can’t ask that. I would however go back to the baby sharing with yous and giving his son the small room. Or let him rent his own place, why did he suddenly change his mind on that?

Moorside111 · 28/06/2025 23:45

CleverLemonCat · 28/06/2025 23:37

Be very careful op. You are already frustrated that the bulk of 'wife work' falls on your shoulders. As you are committed to this relationship, I would ensure that renovations are off the table and that you spend the coming year sorting out his attitude to money and sharing the work load with you.

Personally, I think your daughter should keep her room and maybe the baby and his son share when he is with you.

Also, his son is not more important than your daughter. You have said that he wants the best for his son. Fair enough, but it shouldnt come at the expense of your own child.

I’m in agreement with all of this. I am feeling frustrated, firstly at the imbalance in our current rented home and I think that’s making me stand firm on taking a risk on renovations.

my daughters room isn’t and never was in question. I can honestly say that throughout this time she’s never had to deal with anything other than being my priority.

im more than happy for DSS to share the baby’s room when he’s here, I’d even put the baby in with me so that he wasn’t disturbed. But my partner feels he should have a proper room of his own- and I get that, I wouldn’t settle for anything less for my own children

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

You may not even be allowed to do it depending on how many parking spaces you have. And yes he can’t just get a mate to knock it up it has to follow regs. Check with the council.

Asfor the rest. I would not feel comfortable buying a house with this man. He’s burned though his equity?! And paying half for rent when you do the childcare. There’s no way I’d risk that. You could end up with him taking the money from your house one day if you broke up.

Ponderingwindow · 28/06/2025 23:46

You don’t have to remodel your home.

however, if your husband doesn’t find a way to provide a way to provide his son with a dedicated sleeping space and personal space, you should divorce him. A man who would live somewhere without a place for his child is a man you should not want to be with.

so the question becomes, do you want to break up your marriage over this?

MimiSunshine · 28/06/2025 23:48

Moorside111 · 28/06/2025 23:11

he has more outgoings than me- pays maintenance to ex wife, car payment. My ex h gives me some spousal support so we probably end up with the same money each month
Still, our situations do not mean that I have to carry him. The fact still stands that we pay 50% of the bills each but he also gets his baby son completely looked after, his washing done, tea made etc

His higher personal outgoings are irrelevant. You are subsidising him because you pay 50% of the bills even though he earns a lot more than you. So he is freeloading off you in order to make car payments.

if he can’t afford to lease / finance the car he has and cover a fair proportion of the bills as well as maintenance then he gets a cheaper car.

right now you are basically paying the maintenance or the car by paying 50% of the bills.

CanOfMangoTango · 28/06/2025 23:48

But my partner feels he should have a proper room of his own- and I get that, I wouldn’t settle for anything less for my own children

Absolutely fine. But it's not your job to provide that and i think that's where your frustration is starting to come to the forefront.

Your DP needs to house his son. He cannot demand that your DD gives up her room to accommodate him.

It's your house. He wants his DS to have his own room, he needs to live somewhere that he can do that.

So you and DD in her old room.
DP and his son in second double.
Baby in small room.

That’s not a bad idea at all. My daughter loves having me sleep in her bed- she actually hardly used her room when it was just me and her living together.
also the two older children aren’t always here at the same time, so some nights DSS could have the main bed with his dad and could sleep in daughters room and sometimes she wouldn’t even be there.

the only issue here is that DSS would still not have his own room and considering he’s with us 2/3 nights a week I don’t think this is fair

OP posts:
SpryCat · 28/06/2025 23:51

its not fair but that’s on his dad to provide him with a room by renting somewhere.

user1498809986 · 28/06/2025 23:51

Your partner may not be the best support based on the things you’ve mentioned, however if you’re disregarding all that and are determined to stay with him, I really think you need to consider his son more. I’m not saying you should let anything affect your daughter in any negative way, she definitely needs to be a priority for you, but I cannot understand why you don’t seem to give two hoots about his son? If his son is 50% in that house (which you want to be your blended family home) then surely he deserves some consideration on where he sleeps in the same way that your daughter who is also there for 50% of the time does as well! If this was the other way around and you were moving into your partners house, would you be happy with a solution where your daughter gets relegated to a sofabed in the dining room? By all means give your daughter her old room back, but for the sake of having a properly blended family, get your thinking cap on and decide what you can to appropriately accommodate his son. Either that, or don’t be in a relationship with someone who has other children.

FellInAPotHole · 28/06/2025 23:54

Blimey OP, give your head a wobble
Stop making excuses for why a grown man with a perfectly good job cannot contribute his share of normal living expenses and raising his children.

Whatever you do, do not marry this man and do not provide him any chance of getting a share of your house on divorce

Move back into your home with your 2 kids and live your best life.

Away2000 · 28/06/2025 23:54

It would make much more sense for your partner to use the short time that you planned to stay in the old house to save some of his own money to help with the move to a bigger house. But it seems he’d rather waste time and money badly renovating your garage and making your house less sellable.

Moorside111 · 28/06/2025 23:55

Stripeyanddotty · 28/06/2025 23:40

On the upside at least @Moorside111 knows how her dp operates so if they split and he gets another partner she has an idea of how her son will be treated.

The opposite- he’s doing everything he can to make sure his son has his own space and a nice room to come home to. He pays maintenance and chooses to have his son half the week because he loves him and wants to see him.
if I don’t allow the garage conversion then I suspect he won’t live with me. And I don’t blame him for that- I wouldn’t live somewhere there wasn’t a room for my child.
my frustration is that he hasn’t managed to get shit 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

OP posts:
WhatYaGottaDoo · 28/06/2025 23:56

DP and his son go in a room DP rents from you.

Do not let DP pay for work on the house, this would likely mean he has a financial claim on your property.

He shouldn’t pay towards your mortgage either, as that also would mean he has a financial claim on your house.

DP will be a lodger and needs to pay for half of all the bills in addition to the rent for the room. Put your DD and baby first.

HeyWiggle · 28/06/2025 23:57

Don’t sell your home, keep it for yourself, don’t marry.

HeyWiggle · 28/06/2025 23:58

Just tell him you like the garage as it is, it was only recently done and you want to keep it that way.

Buxusmortus · 29/06/2025 00:01

Moorside111 · 28/06/2025 23:31

Well no, it’s not for me. I have two children, both with good fathers. Either way they both have a room in a nice house in a nice area and a mum who has a work schedule that enables me to do school drop offs and be present during all school holidays. They have and will continue to have a good life.

the mess is from the side of my partner and his son and I’m asking for advice about how much I should support them- but I’ve made it clear that compromising my own children is not part of the deal

You answered your own question here in your second paragraph.

This mess is all of your partner's making. He is the problem. He is not an equal partner, he expects you to carry him financially and practically with housework and childcare, yet demands that he moves into your house and that his son doesn't have a small room. That makes him a selfish cocklodger, not a good man or good partner.

If I was you I'd wake up, realise that you'll have a tough unhappy future with this man, and leave him.
If you won't do that at least tell him that you're moving back to your own home with your 2 children, he can't live there, he won't be getting his friend to do any dodgy building work on your house, and he needs to find somewhere for he and his son to live.

That will hopefully give you the space to realise you no longer want him as a partner.

CleverLemonCat · 29/06/2025 00:01

'My frustration is that he hasnt managed to get shit together so that we can jointly buy a house for us all' That's very telling op. He is expecting you to bear the cost of it all. It's your house, he doesnt get to tell you to make changes to it!
