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.

I think you're wise to protect your own interests.

Ignored124 · 28/06/2025 22:36

Do you want this relationship ? Does he bring much in reality ? I would split up and be a single mum. Keep your house and claim maintenance .

Pinkflower100 · 28/06/2025 22:37

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

theunbreakablecleopatrajones · 28/06/2025 22:38

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.

Justkeepingplatesspinning · 28/06/2025 22:40

Don't let him do a DIY job on your garage. Or his friend. Especially if you're looking to sell in a year's time.
I would be cautious about buying together with him, given he has burned through the money from his house sale. You're doing a lot of providing here.
Stick to what he originally agreed to, that he lives in his own home that he pays for.

OrangeAndPistachio · 28/06/2025 22:44

So he tried to blackmail you into giving his son the bigger room (for his 50/50 stay) then backtracked when you didn't cave?

Is he a good man op?

arethereanyleftatall · 28/06/2025 22:45

I think the penny is starting to drop for you that this man is not a good man at all.
go back to your house, each of your children get a room and honestly…bin this man, he’s no good.

Vaxtable · 28/06/2025 22:46

For a start the garage conversion will require building regs so if he’s going to do it himself I hope he’s up on the regulations required, it’s a lot as a family member found out

and I bet he wants to live in the three bed now as he can’t afford to rent

Do you have separate rooms downstairs? Could one of those be used? If not then sorry he lives somewhere else with his son

and I would t be selling my property to buy a place with him seeing how he appears to be no good with money

Agree . I think OP will have a much nicer life without him.

Minecroft · 28/06/2025 22:46

I would be inclined to live in my 3 bed house with my own two children and let him sort him and his son out !

Fadesto · 28/06/2025 22:48

You don’t want to treat his son and your daughter the same, so there’s always going to be issues. He wants you to pay half the bills and do more than half the childcare, so again you’re gonna have issues. He’s not paying his way, he blew through his savings, and now he’s using your money and wants to move into and butcher your house. He’s shown absolutely zero ability to sort his son as well after all his big talk of renting a house. I think it’d be insane to continue living with this man personally.

murasaki · 28/06/2025 22:49

He wants to build a man cave for himself to use half the week, and his son the rest. Er..
No.

Notfinanciallyresponsibleforyou · 28/06/2025 22:50

You need to take a step back and consider this from a financial standpoint. You own an asset and he doesn’t.

He has no contribution to support a deposit for a new joint owned house. He earns double what you earn.

Are you planning to get married? Are you happy that he will be entitled to half the new house if you break up?

Dont do anything to your house which could potentially devalue it. You said the garage door was newish and expensive.

Madness. Start thinking with your brain! You need to retain some financial independence just in case.

OrangeAndPistachio · 28/06/2025 22:51

I really can't see how this relationship benefits you at all op.

Frozensun · 28/06/2025 22:53

Have you worked out his rent for living in your house? It seems he’s been on a very good wicket with rental share so far! I think the change of heart is because he’s worked out it’s going to cost him - and why should it when you can subsidise him! Draw up a rental agreement to clearly cover arrangements. No, don’t take out your garage door, it’s new, it matches. No structural changes. If you’re acquiescing to the idea generally, hang a wall of curtains internally.

CleverLemonCat · 28/06/2025 22:53

He is on double your salary and yet you pay 50% of all bill's? I would guess you have much less money left at the end of the month but he manages to spend all of his and has already blown through the money he received from the sale of his previous home.

You seem to be in a very financially unequal relationship op. I would be very loathe to sell my own home to provide a deposit for a joint house with him. If things dont work out you still have a home for you and your children, I certainly wouldnt allow him to pay for an extension. He will have a claim on your house and could you afford to pay him off?

I am sorry, but I think you would be mad to sell. Keep your own house and make him saving for his share of a deposit a firm line to buying a joint house. I would also be having a talk about the split of the bills.

GabriellaMontez · 28/06/2025 22:53

"Burned through " ...

How much? What on?

From what you said so far, I feel you should protect your self from this irresponsible man.

Redpeach · 28/06/2025 22:55

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

Eenameenadeeka · 28/06/2025 22:55

I think him renting his own place so he has a room for his son is the best plan here. I don't think the shoddy renovation sounds good so I wouldn't want that in your position, but I don't think it's acceptable for him to not have a bedroom for his son (just like you aren't okay with one of your children not having a bedroom)
It doesn't sound all that equal if he can't contribute to the cost of a home that fits everyone.

2chocolateoranges · 28/06/2025 22:55

Hearing that childcare, bills etc all falls to you then I would be moving into the 3 bedroomed house with my children and let him sort himself and his son out.

However, if you want to convert your garage which would be a good idea then I’d pay a professional company to do it, rather than have a bodge job. I’d rather do this than move.

GabriellaMontez · 28/06/2025 22:56

Pp makes a good point. What rent will he pay ?

yeesh · 28/06/2025 22:56

He is ripping you off left, right & center 🙈

NuffSaidSam · 28/06/2025 22:57

I cannot believe that you have allowed yourself to get in this financial situation.

Are you able to take a step back, read your OP and think what you'd advise the woman to do in this situation?

The DSS is not the issue here. It's your freeloading DP. Do not sell your house or allow him to convert anything. Buy a house together when he has contributed properly to the household, supported your shared child and raised a deposit.

crumblingschools · 28/06/2025 22:58

Why did you have a child with him if you don’t want to factor in his son? You could have kept your house just for you and your DD and have relationship but not blend your family

I don’t think she factored in her dp being a waste of space .
