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.

My home was bought with my half of the equity from the marital home. So I don’t see my exH as still owning any of it
however, it could still be seen as money that I made with my exH- we bought the family house very young for a house of that size and made sacrifices to get it and keep it. We worked and at times it was hard- but paid off in the long run for us

it does irk me to to think that my now DP feels entitled to that money for a deposit- even being annoyed that my house isn’t sold and is stopping us from moving on

we’ve had a few arguments about this already where he’s insinuated that our problems stem from the fact we can’t buy a house because my house isn’t sold. Rather than we can’t buy a house because he doesn’t have a deposit

I think if he brought up you can't buy together because you haven't sold your house i would always answer "where is your deposit?" every single time.

The more you speak about him the more i think you should bin him off - he thinks because your ex is well off he deserves some of it.

tara66 · 30/06/2025 13:19

'' It's all about money'' - Of course it is - to any adult - it's what is needed to even survive independently - an adult knows that if they think for 2 mins.
'' yes'' it's all about money - again - YOUR money as he has none and now thanks to him - you also have none. You should work out what you took out of savings to survive on maternity leave and tell him he owes you half and ask when will you get it?

AcrossthePond55 · 30/06/2025 12:55

Moorside111 · 29/06/2025 22:34

i think everyone just assumes that because I’ve been on maternity that he’s been supporting me. I guess I’m too embarrassed to let anyone know the truth.

DP knows something is up now, we’ve barely spoken today. I’m going to tell him that we need to talk and then I’m going to let him know how disappointed I am that our life has turned out differently to how I imagined (financially) and that I don’t want to continue paying 50% of the bills and 90% of the domestic side. I also won’t be having the garage changed, unless it’s just a temporary space for DSS to put his gaming desk whilst sleeping in the house.

if he can’t contribute more financially, or won’t accept the space I have for his son, then I’m happy to live separately. I think initially he will be annoyed and this is what he will say he will do.

Why even give him the option to move in? There are differences that need to be fixed first. If he moves in 'as is' he will never change. Why should he when he already has his whole body foot in the door?

I'd say "Over the last <insert time frame> it's become apparent that we have differences as far as finances are concerned. I believe you need to make more contribution to the monthly expenses and that you need to meet half of any house deposit. You think this makes me 'all about the money' and that I should pay more because my exH should or does 'support me', which is not true. Financial incompatibility can be a relationship breaker so I think we need to live separately until we can iron these differences out. I also think you need to contribute more to household chores, but that can be a separate discussion if we get the financial difference ironed out'.

JJMama · 30/06/2025 12:33

The problem isn’t the SS and his room; it’s your DH. He’s not stepping up and that’s the real problem. Cut your losses - don’t let him ruin your house, and force a situation you don’t want. If it’s not working now it’s not gonna work long term either.

rainbowstardrops · 30/06/2025 11:58

You sound as if you have your head screwed on and won’t let him walk all over you. Stay firm!

AguNwaanyi · 30/06/2025 11:48

I don't know.

On the one hand, it sounds like your partner has come up with a solution that allows your daughter to keep her room and you are finding issues with it. If he used a different builder and planned the project differently would you be okay with it, or is the real issue that you don't want his son accommodated? I find it hard to believe you treat all the children equally.

However, it also sounds like he is not good with money and you resent having to take on the financial burden of getting you all a bigger house. He did offer to live somewhere else so why not take him up on that?

Kimchiii · 30/06/2025 11:38

Funnily enough, he hasn’t yet called me a gold digger but whenever I do try to bring up the unfairness in our finances he does say ‘it’s all about money for you isn’t it?

With abusive and manipulative people often an accusation is a confession in disguise. So just think about what he has said coupled with his actions. It really is all about the money - for him.

OrangeAndPistachio · 30/06/2025 11:35

@MounjaroMounjaro spot on! And the cost of the materials for said home improvement will increase by £50 each time they mention it.

Kimchiii · 30/06/2025 11:34

OP, I hope your conversation goes well with him today if you’ve not already had it.

I was just thinking it’s awful that he was willing to ask your daughter - whose room it originally is and who is older than his son- to give up her room for him.

If he was worried how to tell his son he could have easily played it as “she’s older son so we have let her keep the big room but we can decorate this other room anyway you want and it’s only temporary etc ”

To even suggest moving your daughter out that room to make way for his son was disgusting.

It also shows his mentality. I suspect him, his son and possibly his ex see you as a bit of a useful idiot that is there to prop them up and ease their financial burden.

Justkeepingplatesspinning · 30/06/2025 11:26

Honestly, @Moorside111 don't let him decide what's going to happen in and with your house. He's walking all over you, playing on your insecurities and knows exactly what to say to insinuate that you're using him for money. It smacks of DARVO behaviour, he's making you out to be the unreasonable one but it's actually him who is taking you for a ride financially.

Shinyandnew1 · 30/06/2025 11:26

And before you know it you'll have a gerry-built garage extension for his son and you'll be stuck with the fucker for years.

Staring he has a claim to your house as he paid for/invested in the garage!

Let this one go.

MounjaroMounjaro · 30/06/2025 10:45

Bear in mind that when a cocklodger is pushed into a corner, he will say anything he can to get out of it. He'll make promises he won't keep. He will insult you. He'll belittle you. In fact just look up DARVO - that's exactly what he will do.

And before you know it you'll have a gerry-built garage extension for his son and you'll be stuck with the fucker for years.

Shinyandnew1 · 30/06/2025 10:37

Your ex sounds like a good man-I would imagine he's devastated that his daughter has to live with such a selfish useless man. Just move back to your house with your two kids make move on-this man is not bringing anything good to the table.

Talkinrubbishagain · 30/06/2025 09:56

He wasn’t bothered about his sn when he spent all his money.

So true!!!!

OrangeAndPistachio · 30/06/2025 08:10

The thing about financial abusers is that they always get too greedy. My mother remarried after my father died and initially the man seemed nice enough. I did notice that she was being extra careful with her money once he came along though , not a red flag in isolation as she always was sensible with cash but noteworthy still.

The beginning of the end for him was when I visited her and noticed that the kitchen was full of own brand foods and the house looked shabby and in need of repair. She has always liked good food and kept a beautiful home. Then hubby appears dressed in expensive clothes and off out to the races for the day , my mum had no money to go out for coffee with me so I paid. We talked and it all came out. She kicked him out soon after.

He got away with taking money from her in various ways for almost a decade. Initially it was topping up the meter , needing to pay the window cleaner etc then progressed to him simply saying that he needed £50 and she would hand it over because she was so used to him taking all of her money.

Funnily enough, he hasn’t yet called me a gold digger but whenever I do try to bring up the unfairness in our finances he does say ‘it’s all about money for you isn’t it?’

he references the fact my exH is wealthy and whilst I was with him, my daughter and I led a very comfortable lifestyle and he knows I never had to worry about money. I just earned my bit, added it to the pot and looked after our daughter- old fashioned maybe but it worked for us and neither felt hard done by.

so because I’m used to having money, when I bring up our finances he makes me feel like I’m being money grabbing. He insinuates that I expected my exH to look after me and now I’m expecting him to.

DP also knows that if I separated from him and went back to live on my own, my exH would up my spousal maintenance so that daughter and I could live comfortably, he wouldn’t even be bothered that it was benefitting my new child. ExH believes that my DP supports me more than he actually does- he’d be furious to know that I used my savings for maternity.
DP always comments that ‘it’s ok for you because ExH will just come to the rescue’

so he hasn’t said the words yet, but I definitely feel like he’s bordering on calling me a gold digger

He sounds utterly deluded. How can he say that you are expecting him to look after you when you have paid 50% of everything while on a much lower income and also while providing childcare for your joint child and his step-child, doing two separate school runs every day.

If I were you, I would end the relationship and you will see him massively panic. He has put all his financial eggs in the one basket of him getting ownership of a large family home without contributing to the deposit and expecting you to pay 50/50 on the mortage and other expenses, despite you earning much less.

You can definitely manage without him. He is absolutely fucked without you.

Needlenardlenoo · 30/06/2025 07:54

You must look out for number one here. This guy does not have your back!

Tiswa · 30/06/2025 07:48

He didn’t support you on maternity and still wanted 50/50 even though you did all the school runs?

here is a brutal truth if you move in with him or continue the relationship he is going to prioritise his son over your daughter and expect you to do the same. Your daughter by all accounts has a loving father exactly where do you think she would chose to go in this situation

saraclara · 30/06/2025 07:23

Presumably the rental income has factored into your present financial situation. If you move back into your home, your income will drop. I think it's important to point that out to him as a reason why you won't be continuing to pay the unfair proportion of the bills if he moves in.

Mercurysinretrograde · 30/06/2025 06:40

OP your last few posts don’t paint a good picture. This relationship sounds like a big mistake for you and your daughter. Definitely get him to live separately for a year or so while you reassess. You need some space to look at this critically. Don’t even offer the third bedroom. Just say this has all caused you a great deal of upset and you will be sticking to the original plan which can be reassessed later.

You do need to have a chat with him, when you do make sure you protect the house, YOUR asset for you and your dc. It’s right that he contributes more, but not at the expense of getting an interest in your home at the moment he has no claim on it at all, you are not married and it’s nothing to do with him. If he actually contributed towards the mortgage and/or any alterations this would change and you could end up losing the house to pay him off if you split in the future and your relationship doesn’t come across bulletproof now.

I definitely think you’re right not doing any alterations to the garage, I also always think it’s weird when people convert most of the garage but still leave the door either do it properly or not at all. I wouldn’t buy a house like that.

Why are your standards in men so low .
You jumped out of the frying pan in to the fire
I'm shocked you had to pay 50% while on maternity leave
I'm more shocked you put up with it
It is ok to be single and have two children
There is no law that says you have to be in a relationship with either of them.
I cannot fathom why you are still letting this man and his son move in your home .
It's bizarre you can't see your better of without him

Cassieskinsismad · 30/06/2025 04:46

@4forksache He was giving maintenance, that he didn't need to give because he had his son 50/50, to his wife.

So no, using her savings wasn't necessary. As a minimum he could have used this money for the maternity leave.

OP also could have had reduced expenses
By living in her own house instead of paying rent,
Not having the higher council tax on a bigger property,
Or the extra heating costs of a bigger property,
Not having all the petrol costs of driving 3hrs half the week taking his son to school then collecting him again.

He also could have reduced his lifestyle and therefore expenses, cutting down to what he could afford. Instead of leaving maternity for OP to sort out alone.

Cassieskinsismad · 30/06/2025 04:29

because I’m used to having money, when I bring up our finances he makes me feel like I’m being money grabbing. He insinuates that I expected my exH to look after me and now I’m expecting him to.

This is gaslighting. It's actually the other way around. He's expecting you to fund his chosen lifestyle. And you've been doing it! Because he's manipulated you into it, made you doubt yourself. He's not looking after you AT ALL. He's all out for himself.

Saying it's all about money for you, that IS him calling you a gold digger, just using different words. It's an insult. And it's disrespectful when not only are you not a gold digger, you're subsidising him, who is one.

The fact you feel guilty etc and question whether you've the right to feel annoyed about these things he does, coupled with your obvious reluctance to give it to him straight and instead tiptoeing around and leaving the final decision about whether he moves in upto him, then hoping he changes his mind about garage conversion so you don't have to tell him no, because you want to avoid the fallout from that...it's coercive control OP. This is the behaviour and thought processes of someone who's being controlled.

He's being so breathtakingly nasty about money, is using you as a cash cow and has managed to convince you it's all fine. It really isn't. A normal reaction to someone treating you badly like this would be to not want them near you. But you're not thinking normally because he's messed up your mind and trained you to accept it. He insinuates you're a gold digger, (whilst he's feeling entitled to all that's yours!)...and... nothing. I expect you waste energy defending yourself and trying pointlessly to get him to see things from your perspective. No anger at the bare faced cheek of him insulting you like that. No rage at the unfairness of the situation of you subbing him financially, with free nanny and maid duties on top, plus taking on ALL the mental load too. Just... trying to explain yourself and justify yourself I'm sure, and at the same time figure out a way to keep him in your life and be a family 🥴. You can't OP, not without being abused.

You've said your baby is a light sleeper and you were happy enough for your partner and DSS to live separately. You've planned for that now that he claimed it was what he wanted (it wasn't, it was a threat (withdrawal of affection) designed to bring you in line and give him what he wants: the bigger room for his son). You feel baby needs his own room, so you don't wake each other all night long sharing a room. You lose that peaceful night's sleep by moving your partner in and giving DSS the baby's room. How much more miserable will this shit show be when you and baby are both chronically sleep deprived? Why do you think you should do that to yourself and baby, just to keep your partner and DSS happy? Why are you putting them and their needs and happiness above that of your own children? You don't have room for them, they need to live elsewhere.

If he moves in I don't put it past him to do work on the house without your consent. He currently owns zero percent of your house. If he carries out shoddy work that devalues it but gives him a claim against it, whatever percentage he gets, it's pure profit to him. From his perspective xyz percentage of a lower value house is better than zero percent of a higher value one. I think moving him in will be a huge mistake for this reason. He can't be trusted.

From what you've said he's seething with jealousy that you own a house and he doesn't. He's barely concealing his dislike for you, acts like he thinks you're a spoiled rich bitch etc and he's determined to take that house from you.

The "lovely him" is a mask, a public veneer of civility. Those snide remarks during your rows, that's the real him. That's what he really thinks of you.

He thinks he's entitled to everything you have and that you not giving it to him is out of order. This is because he doesn't see you as an autonomous person in your own right. You're just a resource for him to use, an accessory to his life (your life doesn't factor into it, you don't exist outside of your usefulness to him). Like a gold bracelet that he can show off to others or sell to release the monetary value of. Or a pair of overalls he can hang on a hook when he's done with them and forget about. You're something he owns.

Everyone is "lovely" when life is going how they want it to and they're happy, it's how people behave when there's an issue and things aren't going the way they want that determines whether they're a good person or not.

Read about future faking OP. He already knew he'd spent his money at the time he first made plans to buy a house with you. He then made no effort to save a deposit to make happen. He keeps talking "equality" but it isn't actually happening. There's nothing equal about your finances and I agree with those who said he's probably squirrelling some away, which is why he hasn't love bombed you into marriage yet. He probably has a big fat pension and that's why his ex wife got 2/3 of the house equity in the divorce, not his generosity. .
