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.

To me it would make sense to have someone come to look at the garage, give a proper quote including any planning etc involved and make the decision from there.
A friend converted her garage, it still had the garage door on the front and a space that they put bikes etc into and then the room was behind it with doors out onto the garden the other end.
It was done by a reputable company, all building regs complied with and added value to their home because the garage wasn’t actually wide enough to get a modern sized car into and open the doors to get out so was just a dumping room.
Your DP can rent somewhere for 6 months whilst you convert the space, and you can both pay towards it, and have it written in that any equity it adds to your home he is to get half of.
I understand that neither of you want to live apart but for a short while until everyone has a space it seems the best thing to do for the children.
You may have to wait a short while for a builder to have availability, but it wouldn’t take long to complete once they were on site.
The other option is to go upwards and convert the loft which is what we have just done. The work was completed in 4 months and we now have another bedroom and bathroom.
I would keep this house and make it work rather then try and buy a bigger one jointly. Perhaps he’s hopeless with money or his divorce left him with hardly anything, you’ve said he’s burnt through the money he came out with but that could easily be done if he came out with little but I certainly wouldn’t be over stretching myself to buy something bigger when what you have is perfectly adequate, can be renovated and most importantly yours.

Cheesesteakyum · 29/06/2025 08:53

It’s nice he wants to take care and see his son so ultimately shows he’s not a bad man but the financials are a worry.

A garage conversion may add value if done correctly but you need to speak to a reputable builder and ensure you have all the permissions.

what about a loft conversion?

I’d also perhaps see a solicitor about your financials as if he pays for improvements to the house he could have a claim on it if you split up.

The biggest problem is your calling your DSS "someone else's child" and prioritizing your DD over them.

This lays the foundation for your relationship with DP to completely implode.

This is what needs fixing.

That’s not the biggest problem at all. DSS is someone else’s child who has two parents to prioritise him.

OP should absolutely prioritise her own child, and herself, over her partner’s child.

edited to add that I think you posted previously about doing the school runs for your DSS didn’t you? I felt sorry for you then and that you were being taken advantage of. I’m glad that stopped and I hope you can put your foot down here as well.

WhyWouldAnyone · 29/06/2025 08:04

That's what any sensible parent who prioritised their children's wellbeing would do. Instead, we have far too many that don't seem to be able to function without a partner in their home, create another family then wonder why things go tits up.

Exactly. Instead of thinking of sex as a higher priority...they can do that at each other's properties on holidays and weekends! That way their property is their own. And there are no complicated issues with who gets what bedroom etc.

Someonelookedatmypostinghistorysoichanged · 29/06/2025 08:43

“””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.””

you also say he’s is perfect

renegotiate your concept of perfect. He is not perfect or you wouldnae be on mn.

He is cocklodger and a free loader, who has a nanny and a fanny.

He is useless with money and now wants to spend yours.

fuck that

Moorside111 · 28/06/2025 23:45

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

He feels that his son should have his own space but at your expense /cost

Zippp · 29/06/2025 08:41
  1. protect your children
  2. protect you financial interests
  3. have a really good honest look at whether your partner is a keeper or a financially incontinent cf.
MadameSzyszkoBohusz · 29/06/2025 08:40

I didn’t even get through the OP…Christ, why are you wasting your time on this chancer? Why do so many women waste their lives, time and money on useless men who are only out for what they can get.

OP, split up, move back to your own house (you own your own house big enough for the three of you, why the hell would you jeopardise that??!) and concentrate on yourself and your kids. You will all be better for it.

Ibelievetheworldisburningtotheground · 29/06/2025 08:33

I wouldn't even let him move in with you and end the relationship when you move out with your children.

He's been making you pay 50/50, when he earns twice what you do and you're carrying the load at home, too.

He only cares about himself. Do not let him near your assets or let him treat them as his.

Or of course there’s this …..

Shinyandnew1 · 29/06/2025 08:35

I’m asking for advice about how much I should support them

My advice would be that you shouldn't support them at all.

An idea OP. My parents just made their garage into a room. They kept the garage door and built a stud wall behind it. They left a small gap for storage. From the outside it looke like a garage, inside its a room. You could put a window in the outside wall if it's dark.
Converting the garage does seem like the best solution here, i just think you need to agree on what work is to be done and by whom.

I agree. Converting a garage is a really good idea. I think in terms of the future value of your house - you need to have it done well.
it feels like this is the sticking point.
your house - you choose the builders and design the main plan and he pays otherwise garage and a burnt space for his son is a great idea!

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!!!

This is the bit that jumped out at me .. and I’d say the crux of the matter.
what did he spend it on? Knowing you’d need a deposit for your 4 bed.

SheilaFentiman · 29/06/2025 08:32

Cocklodger is going too far, IMO.

OP has made some decent choices: renting out her house for a profit (which is perfectly reasonable, it’s a 3 bed house and the mortgage is only so low because OP bought it with equity from the FMH) and renting a 4 bed with DP. She checked with DD before doing this and DD seems to have been happy with the set up.

The incomes seem comparable with rental profit and payment/receipt of maintenance. So maybe 50/50 on bills was fairly reasonable, though should have been thrashed out and agreed.

Things would have ticked along ok (especially now op has put her foot down about DSS childcare) if it wasn’t for the tenants giving notice and the DP spending his FMH equity (though we don’t know what on - if it was training so that he got his current salary, maybe not so irresponsible)

DP hasn’t been brilliant and the room suggestion was poor but he hasn’t been a useless waste of space either.

Shedmistress · 29/06/2025 08:32

he’s doing everything he can to make sure his son has his own space and a nice room to come home to

Apart from it would seem using money to provide for him. All he seems to be doing is making you do everything you can to provide for him.

Georgemiss · 29/06/2025 08:30

You are (rightfully) resentful that your partner is earning double what you earn but is only contributing the same as you towards the bills despite you taking on the bulk of the childcare role for your shared little one. It's unfair on you and should probably addressed. Otherwise, I feel it is spilling into your feelings about accomodating your step son equally.

I have also been a step parent and grew up as someone's step child so I understand how complicated the dynamic can be sometimes. Whether right or wrong, people tend to care for the interests of their own biological children more than their step children, which does have unfortunate consequences for step children which they don't deserve.

As others have said, I wouldn't let your partner make major changes to your garage which by the sounds of it could devalue the property. This house is your security and it would be unwise to tamper with that.

If you all do end up still living together I do think it's only fair that the two eldest have a bedroom each (daughter back in her old bedroom) DSS in the other bedroom and the baby in with yourselves.

I've been in a very similar situation regarding bedrooms where I had a step daughter, my own bio son and a joint baby together. This is the route we took (with the baby in our room until we moved).

However (and it's a big however) my then partner was always fair with money so although I wasn't working much and was taking care of the baby, he respected my time as a care giver so his wages were Our money. We ultimately split 5 years down the line due to other issues but finances etc thankfully weren't one of them.

Longhotsummers · 29/06/2025 08:30

He has a very good deal on all levels here and you are now having to provide concessions ie convert your house, to provide yet another solution for him.
His financial acumen, or lack of it, would concern me a LOT. Let him rent elsewhere while you move into your own home and see if/how he makes efforts to save for your future together.
Do not get rid of your home easily to get him off the financial and family hook.

The mortgage is 600 and you were charging 1600pcm rent?

Wow

Practically, you chose to blend families. You chose to move back to a 3 bed which is sufficient for said blended family.
Fair enough don't let him replace the garage door, but I think you need to get the garage into a room for DSS, or end things with your partner.

This.

He sounds useless and taking advantage of you in general. So there is the option to end it and live with your kids.

But if you are determined to keep blending a family with him then you do need to think about the welfare of all the children.

If you insist on having it both ways, it’s a kid that suffers, and that’s not right. Yes, your DP is more responsible to blame for that, but you are also an adult and have made and continue to make the choice to blend a family with a man with kids.

If you want to live together you need a solution where his son can stay.

Because they have a young baby together and that baby at least deserves a chance to grow up with both mum and dad together instead of a knee jerk throwing the towel in. I have to say I'm sceptical if this arrangement can possibly work long term but the baby is here now and they have to somehow try to make it work.

Yeah but I think most people who are saying for OP to leave mean - “ask him to change and leave if he doesn’t buck up his ideas and stop taking advantage of you.”

Obviously if all the issues can be resolved immediately and he stops treating her so poorly and sponging off her things may be salvageable.

But people are operating on the assumption that he won’t change following their discussion - which is probably true - and that’s why they’re urging her to leave before he adversely affects her finances and assets any more.

LAMPS1 · 29/06/2025 08:21

Your issue shouldn’t be about going out of your way to provide a bedroom in YOUR house for HIS son.

Your issue, as I see it, is that he wants to compromise YOUR (not his) hard earned financial asset, probably depreciating the home into the bargain, without bringing anything to the table himself except a likely bodge job.

Until you are certain that he is bringing an equal amount into the partnership for a deposit then you shouldn’t be risking or even using your asset to house him and his son. If you were good enough to pay 50/50 for rent and utilities, he should be good enough to pay a 50/50 deposit on your future.

He has been careless and thoughtless with his money. He has some financial making up to do to convince you that moving in together again is a good idea.

It’s clear that he was hoping you would forget or at least postpone your decision to move out and has had to back-pedal to accept that you won’t be as cavalier with your finances as he is with his.

You have been subsidising his lifestyle OP by paying 50% of the rent and utilities for a house of his choice when he earned considerably more than you. That was a splendid arrangement for him but he wasn’t thinking of you at all. He continued to allow it and to benefit from it and yet still has nothing to bring to the table.

He still isn’t thinking of you or your future with his latest proposal. How dare he even suggest using your asset to house his son when he has no asset of his own to use. He is really jumping the gun there OP and is hoping that ‘love’ blinds you to it. You need to be very cautious with your next move.

Tell him that you are moving back into your old home with your children who will have a bedroom each and no thank you, but you aren’t ready for the stress of his garage conversion idea for your house. Indeed you aren’t even sure of the wisdom of it and need time to settle back in and think.
You need to get back into a good working routine, ensuring you can provide for your children, while you weigh up your future career and housing options.

Encourge him to buy a small two bed flat nearby and you can continue your loving relationship that way. Point out that you will at least then each have a property to sell before you combine and entwine your more equitable future finances.

MyOtherProfile · 29/06/2025 08:20

I would get a builder to quote on doing the garage and look at that properly as an option. Otherwise it all seems impossible.

  • you want to stay with him
  • you want a room for each child
  • you're moving back to a 3 bed

These things aren't compatible without finding another room.
Our garage was converted to a bedroom before we bought our house. It was all done with the required planning and is lovely.
