To not provide DSS with a room

594 replies

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 actually don't hate the idea of converting the garage, lots of people do it around here and it makes sense long term for space, however I would oversee the work myself and pay for it so he doesn't have a claim on the house.

TBH though I'm surprised you gave up your house so easily to move in to rented accomodation, it sounds like you and your daughter really love it. I wouldn't move out of my home (single parent) without a really good offer as it belongs to me and my kids.

cryptide · 29/06/2025 09:07

Get the garage conversion done by a good quality professional on the basis that your partner pays. If he has to get a loan for the purpose, so be it.

Driftingawaynow · 29/06/2025 09:07

havent rtft
I’ve probably got confused here, but from the sounds of it you both have a similar income when you take into account his earned income and your unearned income?
which presumably means he has been working longer hours, hence you have been picking up more of the work at home? And you split things, 50-50… if that’s the case, it doesn’t sound that bad . Fair enough if you think you’ve been doing too much and have pulled back, sounds sensible, but it doesn’t sound like what you’re describing is horrendously unequal

I would be concerned about his general fecklessness with money and planning, and for that reason I’d be seriously putting the brakes on getting financially enmeshed with him

but aside from that, if you wanted to make it work with all of you in the house, you could potentially set up both larger rooms as a kind of flexible arrangement. You and your daughter in one, your partner and his son in the other and adults hotdesk between rooms as the kids come and go so you also have time just together

It’s a creative solution, but don’t forget the kids are having to deal with live in between two different houses so when you look at it like that, it’s not that horrendous is it?

AirborneElephant · 29/06/2025 09:11

I would be very concerned about merging finances with someone this bad at managing money. If he does move in please, please make sure he signs a cohabitation agreement stating he has no financial interest in your house, especially if he is going to spend money on it.

In terms of DSS, I would ok the conversion but ONLY if it is done properly with the right permissions, correct certificates for electricity ect, good insulation and to building regulations standards, otherwise you are allowing him to damage the value of your main asset. He can pay for that in lieu of paying rent for the first x months.

My thoughts would be she should pay for it so he doesn't have a claim on the house.

SALaw · 29/06/2025 09:12

@Minecroft what if the husband wants to live with “his own children”? That would be his son and the baby he shares with OP.

Greenvases · 29/06/2025 09:13

Lookingafterthepennies · 29/06/2025 09:02

OP have the ages of the children been mentioned? That is relevant - what a 6 year old needs is quite different to what a 14 year old needs. Also impacts how long maintenance will be paid for future planning

I do think you were a bit misleading op in your original post saying DP earns double when actually your money in hand each month is about the same. He works long hours and you have a less demanding job. As long as division of labour / free time is equal when he is home, equal split of the bills is fair. If it’s not then you have an issue.

As to AIBU to say no to the garage project? Absolutely not. Consider it in a years time if done properly but not for now.

Scenario for now, son has smaller room, daughter keeps her room, baby stays with you. Unless - you mention a nursery- is that another room that could be a bedroom or the smaller room?

If you want to have a proper stab at this you should all be together. Plenty of people manage families of 5 in a 3 bed house. i would be wary of selling up and buying with this man until he’s shown you a better commitment to managing his finances though. Like others, it would be useful to hear how much money and how he burnt through proceeds from his house sale and why it wasn’t a priority for him to use the money to invest in your families future.

He blew the money because he always knew he would find some solvent naive woman desperate for a man, who will house him.

These losers that blow all their money ALWAYS latch onto a woman with assets and that can pay their way.

User losers aren't stupid.
They know someone has to pay the bills, they just want to do the bare minimum themselves.

OP was a perfect target.
Pays half and yet is house skivvy, free childcare.

They target desperate women with no self esteem.

Unfortunately it is the OP's poor daughter who will pay the price as this loser now wants to move in with his son and take over her home.

If the OP cared about her daughter she would tell him house his own child separately. The end.

She would protect her home, her childs home, her asset.

She would NEVER marry this loser and she would focus on making the best of this situation.

SALaw · 29/06/2025 09:13

the garage conversation is the best solution but make it a condition that it is done by professionals

Greenvases · 29/06/2025 09:15

Doing a garage conversion with this loser, giving him a claim on her property is not a good idea.

SheilaFentiman · 29/06/2025 09:15

The other thing we don’t know is how much 1/3 of the equity was or how long ago . Obviously burning through £100k in three years more concerning than burning through £20k over a decade or whatever

OrangeAndPistachio · 29/06/2025 09:17

@SALaw if he wanted to live with his own children why then why did he suggest that he and his son get a place of their own? He said that knowing that he'd be separated from his baby. I think that's very telling , very manipulative.

Theroadt · 29/06/2025 09:18

Why not just movd into your own house with your own kids and he can join you if he wants…or not? I don’t think a house from a divorce settlement is designed to help subsidise a new partner who brings little (financially) to the table, is it? I feel sorry for your kids, frankly - put them first not this feckless partner!

This. Why oh why do women in this situation never put their kids first? They just hang on to the first man who latches into them. How comd we are raising women to have so little self-respect?

Absolutely. It's embarrassing and so pathetically weak.

Men do it too, though.

Moorside111 · 28/06/2025 23:00

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

He's not remotely perfect

Stay with him and have a life of resentment

AlertCat · 29/06/2025 09:29

Lookuptotheskies · 29/06/2025 00:31

I'd suggest he has a small house or flat with his ds while you spend the time doing up your house to sell.

Propose you both save during this time, spend as much time together as you all can, and reassess as you go.

I'd not want him to move in in these circumstances and as you say he likely won't want to either.

I think an interim time period where you each have separate addresses is the only way to go really!

This, and check in regularly to see how each other’s savings are going. You’ll quickly see how committed he is to putting an equal share into the home you want to buy together if he’s having to manage his own household while he does it.

You sound pretty sensible, I hope you’re right about this man and that the two of you can find a way to work it out.

FiveBarGate · 29/06/2025 09:30

I think the other relationship issues have been covered so I'll just focus on the garage.

It's not a terrible idea and could add value but his approach to it is all wrong.

I'd decide separately what you want for your property. Is there a rear wall you could add a window? It is not uncommon to leave the up and over door so it doesn't impact the street view and then just have a small storage area

If it is to be a bedroom there are requirements for insulation. This will reduce the size of the room. Is it still feasible? Many newer garages are very narrow. How will you add a radiator, electrics etc? It's cheaper than an extension but still costly. Who pays and if it's him, will that give him a claim on your house?

I wouldn't have any further conversations about this until you decide what you want and what you want.

ThinWomansBrain · 29/06/2025 09:30

not only is he financially abusive, wasted any cash from his own house sale - you do all the childcare and housework because CF has a demanding job?
At lease you've partially seen the light and dropped the school runs and childcare for his son.
Now he is planning to move into the house you own with no thought of contributing to the costs of that, because he was "too busy" to look into accommodation for him and his son?

Surely you'd already looked into sharing the costs of him living in your home for the 50% of time he was in his rented accommodation, just build on that😂

Norwegianwood35 · 29/06/2025 09:30

Are you planning to get married? If you are the protection on your deposit becomes null & void as the home becomes a marital asset.

I certainly wouldn’t be buying a home without him matching your deposit. You shouldn’t be paying 50% of the household bills, the money you get from your ex for your daughter is for her, and shouldn’t be included in the household bills.

If your partner has more outgoings is that because he is bad with his money? If so, that’s on him to sort out.

Please protect yourself.

Secretsquirels · 29/06/2025 09:31

I appreciate that there are a lot of things going on on an emotional level. But, on a practical level what I would do with the house to get an extra room without losing value is:

If the garage doesn’t have a window get a proper decent builder to come and put a window in.

Build out the inside of the garage with a plaster board wall all round. On the side where the door is you need to build this a foot or two inside the door.

Paint the wall, insulate and carpet the floor.

Apart from the window that can’t do any harm to the house, and is reasonably easy for any buyer to remove to return it to a proper garage.

Advocodo · 29/06/2025 09:34

I would be concerned with merging finances in this situation. Please protect you and your children’s financial security.

I also agree with this. t the moment he isnt a team player.

also, regularly check in on how he maintains his home with his son.

Cherrysoup · 29/06/2025 09:38

You’d be mad to let his mate who does shoddy work wreck the value of your 3 bed by making the garage into a bedroom-badly! Temporarily live apart, then he needs to pay equal rent/mortgage, although I bet he won’t, having burned through 1/3 of the house equity! He sounds totally irresponsible and impulsive. Protect yourself, OP.

MascaraGirl · 29/06/2025 09:42

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

@myplace this is good advice. The DSS is being offered a room, just not the one his Dad prefers, beggars can’t be choosers and as you say, he isn’t doing anything extra’ to improve the situation

And I fear the loss of a garage could devalue the house

LotaWyseWomen · 29/06/2025 09:44

Canonlythinkofthisone · 29/06/2025 08:18

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.

I don’t see the issue with this at all. Op and her ‘d’p are currently renting another property, which will be costing even more, probably more like 2.5k. And the 1k is nothing like 1k after she’s paid tax and other associated costs and fees. If she had a 100% mortgage on the property, it would be more like 1.6k and she’d still be liable for repairs whereas the tenant is not.

And she really doesn’t have to create a bedroom because a man can’t be bothered to house his own child. She’s already housing their joint child and he’d told her he wasn’t moving to her 3 bed.
