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.

His Ex must be just thrilled at your spectacular naivety, putting them first.

Absolutely no evidence for this statement , no reason ex should have any idea what OP’s financial position is. Not her circus, not her monkeys

Yes, I used savings to cover my wage for 12 months- they just about got me to the end- I have no more savings now

What a complete mess. So let me get this straight.

OP and OH have other kids and now have a one year old (not a baby btw).

The kids are 50/50 and they all live in a four bed home which is a good size but too expensive.

OH blew through him money so doesn’t really have any but makes twice what the OP does and OP pays half of bills.

So OP thinks the solution is to take the baby away from OH and move back to her home. OP house too small. OH trying to compensate for size by converting garage.

OP unsure of workmanship of OH friend and doesn’t want OH to do this.

So, you finances are unfair, OP does too much of the housework and childcare. Bills are too much. OP thinks nothing of taking a baby away from OH and brother. OH has financial issues. Kids aren’t seen as equal.

Honestly this is a mess without communication or compromise and solutions thats aren’t workable or selfish. Why honestly did the OP have a kid with someone else without resolving any of this?

I am so sorry, you have been taken advantage of OP. He should have been contributing to the cost of his own child. You are in a very vunerable financial position, and I think it seems likely that that will be ongoing. I have been in a similar position myself. I dont think he is the good man that you think he is.

Greenvases · 29/06/2025 13:08

So you have used the last of your financial savings to pay your way during mat leave while he pays his Ex, even though his child lives with you 50/50?????

You really have put a man ahead of your childrens best interests.
You have absolutely put your childrens security in jeopardy.

His Ex must be just thrilled at your spectacular naivety, putting them first.
They both must be.

So sad.
Such awful decisions.
Your 13 year old will see this all playing out in front of her.

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 .

Edited

I would too. He doesn't bring much to the table does he?

This is rubbish, OP. What discussions did you have that resulted in this?

SheilaFentiman · 29/06/2025 13:00

Did you also miss the bit, where they planned to buy a house together? But then he accidentally spent his deposit on a new car for himself?

No - the DP seems to have spent the money in the early days of the relationship, according to OP,

They have a joint child together so when it’s the man with the house in this situation mumsnet is pretty clear he should be putting it all into the pot and sharing.

op is being advised to keep her house, not accommodate the stepson, and even to make her child’s father rent his own house and pay her cms (wouldn’t he see the child at least 50% of the time)

Did you miss the bit where she offered to accommodate his son?

And he declined because the room wasnt big enough?

Did you also miss the bit, where they planned to buy a house together? But then he accidentally spent his deposit on a new car for himself?

FruitSandwhich · 29/06/2025 12:47

Why didn't he buy when he split from his ex ?

If he has a good salary & some assets should have been sit

He had enough assets to create another child

Moorside111 · 29/06/2025 11:10

I do 😊 I’m going to do as advised and ask him to get somewhere with his son whilst he sorts his finances. Or he can pay for the garage (without removing the door) to be done professionally- I don’t think he will do this.

my OP was to ask AIBU to say no to the garage being converted, knowing it then gives no room for his son.
I had an idea but I just wanted other opinions because on the surface the idea seems very wicked step mum and unfair. I care for his son and my instinct is to make his stays with us as nice as possible

I think you are going to find yourself in a tricky situation tbh. You have offered his son the small bedroom which is reasonable as he stays 3 nights a week and your daughter is with you full time, and he has rejected this. The chances are that he will probably agree finally, given the alternative is renting a place on his own and paying all the bills.

Worst case scenario going forward, this will become a bone of contention between you. The son will resent not having a huge room with a gaming station ( backed by his father), your daughter may feel that she is being pressured into giving hers up and be unsettled in her own home. So, a house full of unhappy people.

The above could all be moot if he agrees to rent his own place of course, and I am just an older lady projecting and full of doom and gloom. I do suspect that he will move in with you however, which is unfortunate as you sound as though you are actually looking forward to having your own space again!

FruitSandwhich · 29/06/2025 12:37

You are both legally single with children

Ideally, you should protect your asset (property) for your future & for your children's future.

You stay in your property

He rents elsewhere

He pays you child maintenance

If he is good/saves for a few years, perhaps you can look at buying together in the future

What is the rush now ?

I also agree, do not let him convert your garage now

Protect yourself

You aren’t getting it. For most people, the fact that their partner was proposing something so inequitable - and the current inequitable situation - would be a major issue. Why does he think any of this is okay? Why do you? That’s what needs to be addressed.

A judge would look at what both parties understood at the time, and it's not a huge leap to believe he expected this house to be a family home and 50/50 Producing docs where he's signed his agreement to something else could be perceived as manipulative on your part

Do you have example cases where this happened?

They aren’t getting married and OP owns the bulk of the house outright from long before she met DP. Also, he’s a grown man i a good job and not vulnerable etc I really think the idea that a judge would award the house disproportionately to the facts is scaremongering

Jones v Kernott 2012 is the big one, Stack v Dowden 2007 before it.

Judges can either infer intentions (i.e. decide what intentions likely were) from actions, or even impute (decide what should have happened) intentions if needed, based on what's fair and equitable.

DeathNote11 · 29/06/2025 12:13

I'm getting so fed up of reading about men taking financial advantage of women. It's becoming an epidemic of women having to be the default care giver AND do the lions share of providing. Meanwhile, there's handwringing over 'male loneliness', 'declining birth rates' & older women choosing younger men to avoid being nursemaids to middle aged male medical problems. Is there any wonder?

Shinyandnew1 · 29/06/2025 11:58

I wouldn't want him making any changes to my house. I really think him renting somewhere is the only way forward here,

TheMimsy · 29/06/2025 11:55

Long term could the plan be to save and extend the house so the garage has a room above it? Thats what my neighbours have done so they can stay put with a growing family.

PsychoHotSauce · 29/06/2025 11:55

ChristmasFluff · 29/06/2025 11:16

If he pays towards any renovations on the garage, I believe he will then have a financial claim on the house if you split.

Yes he will, and a pretty strong case too. A garage conversion would add significant value and indicate a common intention for it to be a joint home (because the conversion only happened to accommodate his son). Even if he only added 10% or 20% in value, he could easily make a decent case for 50/50 if you split - because of this context.

It would be a flat no for this @Moorside111 I know you're trying to do the right thing, but this is so dangerous legally. Ringfencing and getting bits of legal paperwork won't mean much in a case like this. A judge would look at what both parties understood at the time, and it's not a huge leap to believe he expected this house to be a family home and 50/50, and in the throes of love, that was your intention too.

Producing docs where he's signed his agreement to something else could be perceived as manipulative on your part and trying to benefit at his expense (whats yours is mine and whats mine is my own kind of thing) relying on his false assumptions. I can predict this going so badly!

Bollindger · 29/06/2025 11:40

Have you actually sat his son down and explained everything.
You could make the garage into a man cave, for day time use only, the son would sleep for 18 months in the small room.
you could ask your DP to put the money he would have paid for a rental into a joint account, he pays half the bills for the house as he will have half the children there.
remind him he would save child support and loss of family time.
you could also buy a cot you can move in and out of the sons room , so you do get private time.

You should be paying for it so he doesn't have a stake in your house.
TBH I don't get the house renovations as a big deal as its quite normal for people to extend or convert the garage or loft. It would also be ok to say that you would buy a sofa bed and give all the children they own rooms. Whats the point is selling if you already have a decent finacial asset you can change.
What I do think is more accurate is that you want to move back in to your house like you never left it and squeeze the others in. To me it feels like you partly want some of your old and no doubt quiet life back. This would suggest that something isn't quite right in the relationship and that your house actually means more to you than money.

Also just to add, your taking your daughter back to a house she loves with her bedroom so you can sell it in a year. Do you not think that's a bit unkind? To get something back she loves only for you sell it.
