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.

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.

This! This!! This!!!

I can't understand how you want to sell your asset to huy a house together with this man?!
He earns twice what you do and doesn't contribute twice as much???
In a few years time when the baby you have together is more grown and you are doing all the childcare, all house chores, you are constantly living paycheck to paycheck and he is entitled to half of the house while living the life of Riley all this time, you would wonder how you got there.
Well, this is how.

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

I was just going to say that. It is a lot when we do dour we had to raise the roof 3 bricks to meet planning as garages are often not the same height as required by planning for rooms for living in. To try to sell after hat work is completed with out having planning would be virtually impossible as the new owners would need to see planning and be sure the work was completed properly . Have you actually spoke. To your daughter about how she feels about this

TranceNation · 29/06/2025 08:07

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.

Ohthatsabitshit · 29/06/2025 08:08

Can you comfortably afford to live in the house with your two children? If so I’d suggest it will work better with him renting somewhere and paying towards the baby. Definitely don’t convert the garage.

Orangeandpurpletulips · 29/06/2025 08:09

Sadmummy3 · 29/06/2025 08:03

Where is your DSS supposed to sleep? I don't think you like him very much as you won't allow your children to be put out at all but object to your DSS even having a space of his own
I'm also not sure you and your partner are really happy. Neither of you seemed to care about living apart for half the week.
You can obviously keep your house and think about your relationship but if you are all going to live together your house isn't suitable. Unless you are hoping that if you say no to DSS having somewhere to sleep your partner will leave with his son.

He's supposed to sleep in the 3rd bedroom that OP has offered. A space all of his own, that she was happy to redecorate for him. But this wasn't good enough for his father.

Daisymail · 29/06/2025 08:09

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!!!

What about what her older daughter deserves?

This country is totally fucked with all these 'blended families'. The poor children.

BlueRin5eBrigade · 29/06/2025 08:12

I'd let him rent a home for him and his son and claim CM for your joint child. I don't really understand what he brings to the table. I would get carry him physically and financially to the detriment of my own children.

averythinline · 29/06/2025 08:12

His financial management seems poor and lack of planning now seriously impacting your main asset..i think you're right to be concerned and there are a number of red flags...
With his much higher income and money from his house and only paying 50pct he should have a good deposit/savings...so wheres all that money gone?
Not sure you should risk your security with someone who seems poor and managing there money.... To be frank he is in no position to make demands on your asset.... Anc certainly not hasty decisions such as changing bits of it...is it impulsive spending thats burnt his cash?
..you have a room for his children... They can share...a baby doesn't care about decor so it could look like the older childs room and maybe you store some of the babys stuff in your daughter's room as its bigger ...or your own.
If you see the relationship as long term then think you need a plan..
Theres 3 dc now so schooling/housing etc
You could make a plan to save this year..... Bank statements on the table .. budget in ur house bills based on costs and proportional to income..
Then time to sell/adapt yours..
No matter what that will take money for fees etc or loft/garage if you decide to stay there.. location sounds great so really think before moving..

This gives you time to see how things work out with your different financial mindsets...before risking your security...

Codlingmoths · 29/06/2025 08:12

Moorside111 · 28/06/2025 23:55

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

Not everything he can. He’s neither saving enough to pay towards a house (after blowing his savings) nor supporting his partner (you) to feel like you’re in a team so you can trust him to contribute fairly financially and practically. Both of these are huge things and mean he cannot provide for his son like he could if he did these things. His first and his second plan was for you to support his son (the older one, you already do everything for his baby). He needs a 3rd plan now.

myplace · 29/06/2025 08:13

Return to plan A, his son sleeping in the room he was offered.

If he wants better for his son, then he needs to step up and provide better for his son.

At the moment, he isn’t doing anything ‘extra’ to provide for his dc. He’s covering his own costs.

I assume he’s finding it much cheaper living with you than alone, so he ought to have savings built up as a result.

He’s financially reckless. Be very careful how you proceed. I wouldn’t marry him, for example.

Tandora · 29/06/2025 08:14

Moorside111 · 29/06/2025 00:12

Mirabai · 29/06/2025 08:15

Why do nice responsible women mess up their lives for feckless men.

He has the financial nouse of a 2 year old.

Move back to your house with your kids, and don’t get financially entangled further with him.

DorothyStorm · 29/06/2025 08:15

Your partner doesnt sound like be brings anything at all to the table. He adds stress and problems to your life and takes more than he gives.

OrangeAndPistachio · 29/06/2025 08:15

Op , he doesn't sound like a good man and father. He's not providing for his son , you are. He was happy to step away from living with your joint child and live separately too. Though I fear that was just a bargaining chip to get you to hand the bigger room over to his son. He's also being a shit when it comes to your daughter , as he wanted her to give up her room for his son when there was a smaller room available for him initially.

I wonder why his marriage ended , and where he was living before you came along. Also this car payment you speak of doesn't sound great either. He's a high earner yet doesn't have any savings and has a car loan.

Either way it's a bloody mess as pps have said.

HopscotchBanana · 29/06/2025 08:15

Moonnstars · 29/06/2025 07:43

I think there are two sides to every story and it is the DSC I feel a bit sorry for here.

You have said there is no way you would compromise on your DD not having a room, so surely you can see how he feels about his own son not having a room where ever you live.

It is not clear whether you owned the house with out your ex or whether it was part of your divorce proceedings but if so that is where you gained and he lost to his ex in her getting the majority of the money.

You say he has more outgoings - these include money to his ex, something you are also in receipt of from your ex.

The things that are worrying are
What did happen to his money? You aren't very clear whether before meeting you he had to rent alone and the high costs of this meant it ate into his savings or if for example the ex got the family car and he had to buy a new one. If he did simply spend recklessly then that is different.

The split of the bills. Is he actually a higher earner or not. Considering all your posts it sounds like you both bring in the same amount to the household. I think you need a financial review and see things overall as to where money goes and don't just focus on his job earns more. If you have the same money coming in from whatever source then actually you are equal. In reality if he has more outgoings as gives money to his ex, then he would have less spending money than you so actually he is at a disadvantage.

Why is he giving money to the ex if the custody is 50:50? Normally if split equally no one pays?

Division of labour. I don't understand why you allowed him to get away with doing nothing. Fair enough you do the dinners if home earlier to sort this, but are there jobs he can do at weekends?

Check out the prices in you area of 3 bed compared to 4 bed. Quite a few people where I live converted their garages but this is in line with other properties in the street where some didn't have a garage in the first place. I wouldn't say it loses value if done properly and this could then be the solution to needing a bigger house. Why are you insistent you must move? If the current house you own is in a good location this could be a good solution.

I think she called it 50/50 but later says the DSS is there 2-3 nights a week.

You have said there is no way you would compromise on your DD not having a room, so surely you can see how he feels about his own son not having a room where ever you live.

Sorry but bollocks to his "feelings" in the real world you need to pay for your child's housing needs.

OP is allowed not to compromise. It is 100% her property. He is effectively homeless, by splurging all his money on himself and a car instead of putting money aside to house his child. Not OP's problem, the boy's got a mother to stay with instead of feckless dad.

By the way OP, you do realise you are basically subsidising him right? By paying way over your share for things he could do/afford without you, you are doing no different than effectively directly paying for his fancy car each month. Where's your fancy car...

I know you don't want another relationship with dad out the house, but you truly can't see the wood for the trees here. Where as this hero? He saw you coming.

No one falls in love faster than a man with nowhere to live...

Kimchiii · 29/06/2025 08:18

I agree it’s a mess.

Random thought but as an Eastenders fan it’s one thing I dislike about it. The way it normalises blended families so much without showing the many challenges children face in blended families. Yes it shows general drama and dysfunction for entertainment purposes, but overall it doesn’t specifically address the impact on children suddenly having to move in with another family or not having a bedroom when they go and spend weekends at their other parents or having an unrelated adult about in their space.

I’m not saying anyone is going out and making decisions solely based on Easties but I do believe media can have an impact on social and cultural norms.

Luddite26 · 29/06/2025 08:18

Well I've read your replies/justifications and I am not a judgey person.
If you are determined to make this work I would have baby in with you for the near future put dss in the smaller room as you first proposed. Don't touch the garage.

But in your own interests I don't think DP is putting in enough effort and you would be financially better off without him.
He has let you down spending his money going forward he needs to improve or he's not being fair to you and no matter how much you compromise on his failings you are worth more.
He sounds manipulative and you seem like you can manage so remember you can and don't let him take anymore from you time he stepped up financially.

Moorside111 · 29/06/2025 00:22

I had a large deposit so it’s small mortgage £600 that I can easily pay myself. The rental income paid this and gave me an extra £1000, but the rental on our larger property is so high that my half swallows any rental profit up. I won’t be any worse off moving back

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.

Icreatedausernameyippee · 29/06/2025 08:18

Live apart for the year. It seems like the best way to move forward.

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.

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.

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.
