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.

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.

Agree.

I really hope the daughter reaches out to family, her father, her own teachers about what a mess she is being exposed to.

As yet, there is no mess! Her mum has used her savings up on maternity leave, which is unwise, but DD is securely housed in a rental property with her own room and will shortly be moving back to a prior property her mum owns with a small mortgage, and getting her old room back. There may be a garage conversion or her baby sibling may share with parents for a while.

What is it DD is supposed to reach out about?

This ^

my daughter has a lovely home with her dad. She has a lovely home just down the road that I own. Neither me or her father struggle financially- she has more than most 13 year olds have, including a horse she gets to visit and ride almost every day.

She also has a lovely room in our current rented property- which she was eager to move into- she merely had to demonstrate a tiny bit of reluctance and the move would not have happened. She gets on well with my partner and his son and really is a happy, well rounded girl. Happy at home, happy and doing well at school.

she is excited to move back to the old house, but mostly because one of her best friends from the same school lives on the street- it is not because she unhappy anywhere else.

if we were to buy another new home with DP I’ve no doubt she would be excited again. The new house would be in the same area she grew up in.

ive taken no risks with my daughter. She isn’t privy to my financial decisions so hasn’t had to ‘witness all of this’

I moved into a rented home with my partner first, so as not to risk my owned home. If it goes wrong then that’s life, couples split all the time. But I do have a good income, a suitable home so I can’t see how I’ve made bad decisions- even as a teacher 😆 who by the way make plenty of daft decisions

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

OP,
This is a shared child. You were in a vulnerable position and unable to work due to care of a shared child.

You are not supposed to be contributing financially at this time as you are contributing bodily ! You have risked your health to give BOTH of you a child. He carried none, really none, of that burden.

I believe this is another form of Overfunctioning on your part. You have put yourself in a vulnerable position by depleting your savings.

It is time to change how you deal with money as a couple

There is a very good podcast on Spotify called Money For Couples by Ramit Sethi. A good couples counsellor can also help here.

tara66 · 29/06/2025 13:41

Tell him you have reflected on his personal financial history and also on your own since you have been together and you find because of him you are at a considerable financial loss and going forward you are not prepared to put yourself in any situation where you may experience further loss because of him - very adorable though he may be. Tell him he needs a rich woman not a school teacher!

Rabbitsockpeony · 29/06/2025 13:44

Moorside111 · 28/06/2025 23:01

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

He really isn’t, he’s financially abusing you and trying to manipulate you to get what he wants. Not a good man at all.

allthemiddlechildrenoftheworld · 29/06/2025 13:44

@Moorside111 I am still struggling to understande why he gave his ex 2/3 of the profit from his previous house????? why???? his son only comes rarely and doesnt live with you full time so why should he have a big room for a weekend stay? why is he still paying his ex if he is supposedly having his son 50/50? is he overpaying her?? cant see why you both end up with the same money when he only has his car! I would also NOT let him contribute to the mortgage of your house! charge him rent and give him a lease instead!

BooneyBeautiful · 29/06/2025 13:29

Is it an integral garage? If so, by keeping the existing garage door in place, you won't have anywhere to put a window, and you will need a window to meet planning regs.

Yes it’s integral- there is garden on the other side of the garage though so a window could be put there.
it would have to be looked into properly and perhaps it’s not even viable. I highly doubt DP will want to go to that much trouble anyway.
I think he will either rent somewhere of his own or accept the smaller bedroom for his son (which again, is a fine bedroom that I’m sure children across the country live full time in)

at this point and after hearing everyone’s opinions, I won’t be disagreeing he says he will rent somewhere else 😊

That's awful. Your contributions should have been reduced while you were on maternity leave. Your partner is the net beneficiary of your relationship as you are making all the sacrifices/compromises and contributing to the family finances disproportionately in relation to your lower income while doing all the wife-work and child care for all the children, including your step-son.

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 .

Edited

This would be my plan, in what is essentially a rather messy situation.

PeggyMitchellsCameo · 29/06/2025 14:00

Do you really love this man @Moorside111 and see yourself spending forever with him?
Have you ever discussed marriage?
It is not great that you ran down your savings to fund your maternity leave.
Does his career involve any stability eg a decent pension?
I have only ever been in a (short) relationship with a man who recently divorced with two young daughters. He was self employed and hid a lot from his ex, and then blew what he should have shared with her on a very expensive Mercedes. No pension, interest only mortgage he was… a financial advisor! He spent money like water, was seen as being very generous, but I think he saw the end of his marriage as a chance to indulge himself.

Christ almighty. OP, what the fuck are you doing?

This prince among men hasn't even dipped his hand in his pocket to cover your expenses during maternity leave. That should have been a big waving red flag. He will bleed you dry financially. I bet his ex has some things to say about his attitude to money as well.

Wake. UP.

TheBewleySisters · 29/06/2025 14:27

Would the proposed garage conversion have to be reverted when you come to sell? Some buyers would be looking for a place with a garage and not an extra room. Or is there a drive where people can park?

Luddite26 · 29/06/2025 14:28

He's been a bloody cheeky fucker. Yet people point the finger at OP.

LAMPS1 · 29/06/2025 14:29

This man already owes you £’s OP, big time.
Did he never suggest you shouldn’t be using all your own savings to give birth to and rear his child for the duration of your maternity period, and to support him and his child?

You have taken on far too much financial responsibility. You didn’t need a big draughty house that eats up your money. You already had a good life. Combining your lives should have cost you far less, that’s supposed to be the idea, but it’s cost you more…..all to his (and his ex’s) advantage.

Being a single mum in your lovely old familiar home with your two children will help you start to build up your lost savings again … for DC’s futures and your retirement. That has to be your priority.
Don’t spend a penny more on that rental than you need to OP. Move out as fast as you can.
Do a new budget based on your own income.
Let him house himself and pay you maintenance. When he objects, saying he wants to be with you, tell him you just can’t afford to house him nor subsidise him in the way it has turned out for you.
He has brought nothing to your table so far …to the contrary…he has cost you dearly. All the financial benefit has been his.
It’s sad he has ruined it by being so unthinking.

Luddite26 · 29/06/2025 14:32

He rightly so pays ex CMS and let's you use your savings to cover the time you have with his children while he earns his good wage we he keeps a big chunk for his own fun.
The fucking liberty.

VickyEadieofThigh · 29/06/2025 14:35

I'm still agog that he won't countenance his son (who's younger than the OP'S daughter) in the smaller room but thinks it's fine for the daughter to have it.

That’s not entirely accurate.

He suggested that his son and our baby could have the second double room and my daughter have the small room.

If one child is sharing with the baby, it makes sense for that to be in the bigger room.

TakeMeDancing · 29/06/2025 14:38

Any man who thinks it’s a good idea to spend the equity from his house sale on a holiday and a car, rather than rolling it into a new property to house his own children, is a walking red flag.

outerspacepotato · 29/06/2025 14:40

"if I don’t allow the garage conversion then I suspect he won’t live with me. "

If you don't let him fuck up your biggest financial asset, he won't live with you?

You're afraid if you say no he'll dump you.

He'd be doing you a fucking favour.

He's already financially fucked himself and he's slowly bleeding you dry and wants to fuck up your biggest asset and devalue it. You spent your savings on your maternity leave when he should have been paying. What if you need an emergency big repair on your home? He wants someone who's already done shit work at your place to do extensive shit work. Is he a licensed and bonded contractor? If he or friend have an accident or cause considerable structural damage to the garage or house or adjoining property, who will be paying? You don't have savings anymore.

Girl. You're merrily skipping down the road to financial hell and taking 2 kids with you for a feckless at best, predatory leech at worst, cocklodger who doesn't pull his weight in any area.

Bananalanacake · 29/06/2025 14:52

I usually say keep your money to yourself and live apart but a little difficult when you have a DC together.

InterIgnis · 29/06/2025 15:03

Financial compatibility matters. A lot. It’s all well and good saying that money shouldn’t matter when it comes to love and that it’s shallow to consider it, but this is exactly the type of situation considering it helps you avoid.

You’re being, and have been, taken advantage of financially. Allowing this doesn’t make you virtuous, it makes you a mug. You have been unreasonable to yourself in this relationship, but YANBU unreasonable in drawing a line when it comes to your house.

outerspacepotato · 29/06/2025 15:13

"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."

Bangmaidnanny.

"he has had his son 50/50 for the past few years and still paid maintenance. This was only possible by me doing a couple of school runs a week and providing childcare during school hols (I’m a teacher)
during maternity leave I stopped doing this as my baby was being in the car for 1 1/2 hour round trip, after dropping my own daughter off and then DSS. The children are at different schools with DSS being further away. There was no way I was keeping that going when I was back at work and also had to factor in a nursery drop before I even started my own "

He subsidized his son on your back. Why was he still paying maintenance but had you spend all your savings during maternity leave? And you had to run around doing his school runs to the detriment of your baby.

This guy is not the find you seem to think.

" I moved into a rented home with my partner first, so as not to risk my owned home. If it goes wrong then that’s life, couples split all the time. But I do have a good income, a suitable home so I can’t see how I’ve made bad decisions- even as a teacher 😆 who by the way make plenty of daft decisions"

You were paying your mortgage and instead of putting the rental money away to cover any emergency or necessary repairs, you were spending that and your child support and your savings on another house so you could live with this guy. Your relationship has worsened your financial profile quite a bit. Two kids now, a house in need of some renovation, and no savings at all. How are you going to finance those renovations? If he pays, he could get a claim.

Energywise · 29/06/2025 15:16

Don’t be a stupid woman. You have a house and security for BOTH your children. Don’t be a fool and give this up for a man.

being a good mother is putting your kids first - their security, happiness and well being is your priority. Not this man and his child.

I hope you see sense and wake up.

OrangeAndPistachio · 29/06/2025 15:20

I wasn't completely convinced that he was using you until you answered my question about your maternity leave finances op.

I'm sorry , but he's taking the absolute piss out of you. My partner and I kept our money separate until I went on mat leave. We then changed things dramatically and pooled our resources. Having a joint child changes everything.

Your partner is not a good man. He will ruin you and not give a shit while he's doing it.
