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.

Moorside111 · 28/06/2025 23:11

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

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

Why? He doesn’t just ‘get’ these things out of the ether. You are doing them, whilst still paying 50% of everything. Why? In what way does this seem equitable to you?

MumAsYouAre · 28/06/2025 23:18

He’s onto a really good thing, isn’t he? You’re paying half the bills when he earns double and you run around doing all the house stuff/childcare.

And that’s the tip of the iceberg, given everything else you’ve said. So many red flags for one guy!

Stripeyanddotty · 28/06/2025 23:19

I feel sorry for the children. All 3 of them.

Pallisers · 28/06/2025 23:19

So you and your daughter moved out of a nice home that she loves near her school and friends so you could waste money on renting a house with this man and provide some childcare for his son.

Start putting your daughter's needs and your own financial interests first.

Like a pp said. What a mess.

SpryCat · 28/06/2025 23:20

I would look into how much planning permission would cost, getting a qualified builder in to do the work and tell him you can’t afford it. That you’re not prepared for a bodge job and so he will have to rent a house for him and his son. That was his original plan, or should I say, threat! Once he realised you wouldn’t turf your daughter out of her room. He needs to step up for his son and not expect everyone else to. He rejected your idea and you’re rejecting his because it would cost too much. When you put your house up for sale, it might put a lot of people off as they’d have preferred a garage.

Slightyamusedandsilly · 28/06/2025 23:22

You move back into your house. You pay all the bills for it. He can stay over when he doesn't have his son.

He stays in the current rented house. Pays all the bills for it. Lives there when he has his son.

GertrudePerkinsPaperyThing · 28/06/2025 23:22

I read the title and thought you were bound to be unreasonable, but once I read the post absolutely not unreasonable.

I would separate from this man and go your separate ways. He can see the baby for contact as he gets older as with his other son, and can rent his own place.

He’s already on far too much of a good thing with the financial split as it is, but now he wants to live in your house for nothing and make changes to suit himself and his son? No.

Blondeshavemorefun · 28/06/2025 23:22

So he’s used to you paying half of rent /bills of shared house even tho he earns much more

now reliesed that he’s gonna pay all rent and bills of a house for him and his ds and thinking ouch

protect your assets

hes somehow pissed away his share of profits from a house from previous relationship and now wants your money to fund a home for you all

and don’t marry this man

arethereanyleftatall · 28/06/2025 23:23

I am absolutely blown away op that you can’t see that he is using you. That is literally madness to me.

Herberty · 28/06/2025 23:23

If he moves into your house he could claim a share of the equity if you split up by saying he has a beneficial interest in the property by carrying out home improvements.

Don't let him do the work - it will be impossible to sell it without building regs and you are creating legal issues.

If he moves into your 3 bed get him to sign a cohabitation agreement that says he has no financial interest in your property and also says how much he will be paying in rent and household contributions per month. Get him to do that before he moves in as he does not want to rent a property from a landlord so you have some power at the moment - once he moves in he will expect the best room for his son and not want to pay a fair share because it is your house - so you will be subsidising him.

Moorside111 · 28/06/2025 23:03

This is how I feel

And that was Plan A up until today, when unsurprisingly he turned out to be full of shite.

He's also a chancing bastard who's been taking you for an absolute ride with the 50/50 bill splitting scam.

Whatever you decide to do, please do it on your own terms - he holds no cards whatsoever here. And please, for the love of God, DO NOT let him and his cowboy mate vandalise your house!

Moorside111 · 28/06/2025 23:16

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

Can you have an extension,loft maybe?

Shinyandnew1 · 28/06/2025 23:26

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

So, is that going to carry on, but you'll also pay 100% of the mortgage as well?

He stays in the current rented house. Pays all the bills for it. Lives there when he has his son.

I don’t think they should do this. It would make the DSS feel like he’s the problem when the actual problem is his Dad!

And why should this man live with OP part time when he won’t be paying bills for that house.

He needs to rent his own place, and have contact with the baby as he gets older - could look like visiting at OP’s house during the day at first, but gradually working up to having him at his own place.

On the above plan, when does DSS get to spend time with his brother?

She is still near her school and friends in the house we rent. She likes both my partner and his son and was told that if she didn’t want to move in with them, all she had to do was say- I told her I didn’t even need to know a reason. She wanted to move in with them and they all still get on.
At no point ever has my daughter been compromised. She will always have a home, in the area she’s grown up in. I’ll always make sure she has a nice room, just as she does at her dad’s.

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.

Yeah, he didn't seem to mind living apart from you when he wasn't immediately offered the best bedroom for his son 🤔

Can you give some examples of actions that make him a 'perfect husband and father' other than this? Just because it's hard to imagine it based on the thread so far.

Devianinc · 28/06/2025 23:29

Moorside111 · 28/06/2025 23:01

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

But does he want what’s best for you, that’s the bigger question. I’d live apart until he can save some money to buy the ideal house together. It just sounds to me like you’re the only one giving up anything here. He’s sounds like cocklodger. Think long and hard on this one and have everything in writing and ring fence your house before you go any farther with this guy.

Same. I am genuinely baffled by this thread.

Stripeyanddotty · 28/06/2025 23:17

What a fucking mess.

Well no, it’s not for me. I have two children, both with good fathers. Either way they both have a room in a nice house in a nice area and a mum who has a work schedule that enables me to do school drop offs and be present during all school holidays. They have and will continue to have a good life.

the mess is from the side of my partner and his son and I’m asking for advice about how much I should support them- but I’ve made it clear that compromising my own children is not part of the deal

BeMoreAmandaland · 28/06/2025 23:31

No, no, no, no. Just no.

He's got you right where he wants you. Do not enter into any financial arrangement with this man and absolutely do not sell your house in order to do so. You be giving up yours & your daughters security for someone who cannot be trusted financially and does not have your interests at heart (let alone your best interests).

Devianinc · 28/06/2025 23:31

Protect yourself for your children’s sake. His son already has his own room in his mothers house and will probably not be coming around once he hits 16 bc he’ll want to be with friends not his father or you

Moorside111 · 28/06/2025 23:32

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

I knocked through the dining room into the kitchen so there’s no seperate dining room now- but still I’m willing to put a sofa bed in wherever is best. Dining room, nursery etc

Hi OP,

I agree with the other posters on here that you have not been treated fairly.

Has your partner given any account of why he’s failed to find accommodation for his son after he said that’s what he would do?

I think your instincts are spot on. It is up to your partner to provide for his son and he has failed to do this and is now trying to make this your problem.

You have very little to lose by stepping back at this point and making clear his solution (converting your house) won’t work. If he is decent as you say, he will step up and do the right thing

Itsrainingloadshere · 28/06/2025 23:36

As others have said you will need to meet Building Regulations standards if the garage is converted and it will need to be officially signed off by the inspector.

if you convert and don’t get the sign off you are likely to have trouble selling it as most people won’t touch a property where there’s been work done with no Building Regs sign off.

CleverLemonCat · 28/06/2025 23:37

Be very careful op. You are already frustrated that the bulk of 'wife work' falls on your shoulders. As you are committed to this relationship, I would ensure that renovations are off the table and that you spend the coming year sorting out his attitude to money and sharing the work load with you.

Personally, I think your daughter should keep her room and maybe the baby and his son share when he is with you.

Also, his son is not more important than your daughter. You have said that he wants the best for his son. Fair enough, but it shouldnt come at the expense of your own child.
