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.

This seems like a very one sided relationship.

As he seems rather irresponsible with money then I wouldn't want to be buying a house with him.

His son can have the smaller room and your daughter shares with the baby.

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

Yes I’d like to have a relationship with him. In every other way he’s a perfect partner and father. I just wish we could be more financially equal

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?

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

OP posts:
Slightyamusedandsilly · 28/06/2025 23:03

He's a cock lodger. You can rationalise it if you want, but he's using you.

I do feel sorry for his son, but that is on him. It's a shame you didn't wake up to what a user he is before you had a baby with him, but you are where you are.

Tell him to rent somewhere. DSS can either stay at his mum's 100% OR sleep on your sofa until he's found somewhere. Put it back on the boys father to sort it out.

And FFS protect your deposit on the new house. Get legal documentation drawn up. Because when (not if) it goes tits up, he will want half otherwise.

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 had no idea about regulations, but I’ll discuss this with him and this on its own might be the end of the idea

Autumn1990 · 28/06/2025 23:05

I would stick to your plan and have a room for each of your children. You need to work to pay the bills on your house. Don’t get married to him. You are in a good position with a house. Continue the relationship if you want but keep finances separate. I know that unusual on MN but if you’ve got the better hand it’s better!
His son could sleep on a sofa bed. If you’ve have a dining room a sofa bed could go in there. Obviously if you’ve don’t want that DP would have to rent a flat

Moorside111 · 28/06/2025 23:05

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.

My plan was always to safeguard my deposit when buying a house jointly- I would want something putting in place to say that I owned my percentage of the house deposit and then a further 50% of what was made jointly after. He is ok with this

AboogaBooga · 28/06/2025 23:06

I would maybe come down off your high horse a bit. You got your house from your divorce settlement and he lost out in his settlement like most men do.

Why did you have a baby with someone you obviously don’t even like? of course his son is going to need a room. He shouldn’t have turned his nose up at the first offer of the small bedroom but now what is your suggestion? No room at all? Where should he sleep half the time? Or should your “partner” dump his son in favor of you and your new family.

id just break up at this point. Enjoy 50/50 with your new baby too. What a mess.

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.

We haven’t had a discussion about what he would pay towards my mortgage and bills. He only brought up the idea of moving into the house today

Never compromise your own financial security for a man. You have two children to think of.

How are you going to split bills when/ if he and DSS move in? I expect he will refuse to pay anything other than a contribution towards bills and certainly no rent.

Do NOT let him pay for any renovations. This house is yours, it's your asset. Any renovations come from your bank account.

No relationship is perfect but financial incompatibility is a big one. Wishing things were different is not going to help.

19lottie82 · 28/06/2025 23:08

I think that, yes, his son does need his own room if he’s with his dad 50/50, BUT this isn’t your problem to solve, it’s his fathers.

The obvious solution would be for him to pay someone to covert the garage, properly. A DIY job is not an option. As a pp mentioned, if he doesn’t have the cash, he will need to get a loan. However, I would get all the financials sorted out before you agree to this, he needs to contribute fairly to the running of your joint household.

ByMerryTiger · 28/06/2025 23:09

You’re being taken for a ride. You’re covering half the rent and bills despite earning half his salary, while also doing most of the childcare and housework. And now you’re offering up your only asset, your renovated home, to be hacked about so his son has a bedroom?

Why? Honestly, why are you even considering this? In what ways is he a ‘perfect partner and father’?

He has no deposit because he spent through his equity. That’s not your problem. You’ve got a child to care for and a daughter whose stability you’re rightfully prioritising. She shouldn’t be shuffled into a smaller room to make space for someone else’s child, especially when his own father won’t make any real sacrifices.

Suggesting your daughter take the small room so his son can have more space is a complete piss-take. And now this DIY garage conversion? With a mate you know does shoddy work? On a garage you recently invested in? You’d be vandalising your own property to solve a problem he created. Again, WHY?!

MC846 · 28/06/2025 23:09

Don't sell your house and buy a new one with him, you'll just be giving half your money to him. Move as planned with your children, he needs to go into rented with his son, that was his choice when he spent his money 🤷‍♀️

hellywelly3 · 28/06/2025 23:10

What is he bringing to the table? Let him rent somewhere for himself if he wants.

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.

he has more outgoings than me- pays maintenance to ex wife, car payment. My ex h gives me some spousal support so we probably end up with the same money each month
Still, our situations do not mean that I have to carry him. The fact still stands that we pay 50% of the bills each but he also gets his baby son completely looked after, his washing done, tea made etc

Unexpectedlysinglemum · 28/06/2025 23:13

Don't ruin the garage it will impact value of your home

His son could go in with the baby when he's here? Or the baby could move in with you when no big kids and sleep in a siblings room when no siblings there? Baby won't care about having own room yet.

It's your house. How much is the mortgage? What will he be contributing?

You need to have a proper financial discussion before you move and consider buying. It's not fair that you earn less and pay 5050 if you're an equal family. He should be paying more.

You might be financially better off if you split up and he pays child maintenance (unless he wants baby 5050, but sounded like he was planning on leaving baby with you when he was talking about renting somewhere for him and his son).

I would be very wary of mixing finances with this guy. Don't marry.

Gothzilla · 28/06/2025 23:13

He said he doesn’t want to live apart from me and our baby

No he’s realised that he’ll be financially better off living in your house.

I don’t understand why you’ve been paying 50/50 when he’s a much higher earner. What’s the reason?

Unexpectedlysinglemum · 28/06/2025 23:14

He also needs to do more house work or hire a cleaner for his half

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

When we blended our family and had a baby together it was based on the agreement that we would rent for a year or two in a house large enough and then buy somewhere large enough. Knowing what his wage is and the impression he gave me was that we could make this work.
but financially I now have to move back to my home in order to sell it. I can’t market it with tenants in and we can’t afford to pay rent and my mortgage on an empty house whilst it sells

But if they are planning to move shortly you don't want to ruin the value on the home by losing that expensive new door.
