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.

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

Needlenardlenoo · 30/06/2025 07:54

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

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.

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.

Talkinrubbishagain · 30/06/2025 09:56

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

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.

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 11:26

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

Let this one go.

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.

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.

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 11:38

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.

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?

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!

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.

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'.

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?

blackpooolrock · 30/06/2025 14:44

Moorside111 · 29/06/2025 19:20

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.

Cassieskinsismad · 30/06/2025 15:08

The problem with expecting him to change is, he won't. He is who he is. We all are, once we're adults. If he has to change his fundamental viewpoints to be a suitable partner for you, it means he's currently unsuitable. The thing about fundamental viewpoints is they form the core beliefs you hold and massively affect your personality and behaviour.

Occasionally people do change, but it's because something in life has brought them to a place of self reflection and mental growth. It's never because someone else wants them to. People can't change for others, it only happens if they want that for themselves.

He may pretend to have changed, he may even go so far as saving up a deposit (probably whilst continuing to insult you, resent you and make out you're unreasonable for expecting it), but as soon as you've moved in together he'll revert to type. There'll be cashflow issues on his side that means you have to pay the bills entirely yourself "this time" (every time, with the occasional contribution from him that he'll lord over you every time you raise the subject of money). Or there'll be a holiday booked, deposit paid (by you, and he won't pay you back his half) then when the time comes he'll mysteriously not have the funds to pay off his share of the rest, the DC are all looking forward to it as were you and you'll be thinking how you can't be the evil one cancelling the holiday, so you'll pay it all. His car will break down and he'll drive yours to work, because you travel by train, WFH or can get the bus as it's not as far away as his place, so you don't really need a car...the only way to get your car back (because you'll be too scared of the fallout to simply say he can't use it) will be to have his fixed at your expense. There'll be all the times the DC needs something mundane and you just pay it, every time, because it doesn't seem worth the hassle and sulking if you ask him for money towards it and think anyway maybe you're being petty because he's "a good dad" because he always love bombs them with expensive presents at Christmas (which he expects you to pay half for!) and fun days out (where he "forgets" his bank card so you end up paying entry or somehow he "can't afford" lunch so you pay to stop the DC mithering endlessly from hunger).
"Oh how do I not love thee? Let me tell shaft you in a thousand different ways". He ain't no Shakespeare OP.

OP, you know nothing about his finances except that he talks a good talk but when it comes to it he can't walk the walk. You know he's happy to prioritise giving his ex wife handouts while leaving you to fund your maternity leave as if the baby was nothing to do with him. You don't know where his money goes every month. You know he looks solvent but you also know that could be an illusion, as it was when you first met. You don't know if he's squirrelling money away in a pension or other accounts you don't know exist, then pleading poverty and getting you to pay 50%. You don't know whether he's run up a pile of debts again, if that's how he habitually lives, upto his eyes in debt his entire life with no plans to ever pay it off unless he comes into a windfall.

When you rented out your house for £1600, with a mortgage of £600. That £1k over should have gone into an account to pay the tax on it, any house repairs or certificates/checks needed as a landlady, and the remainder kept as an emergency fund in case of severe damage or rent arrears.

You got lucky with your tenants. If those tenants had trashed the place, turned it into a cannabis farm or not paid the rent for the entire duration of the about-a-year-long legal eviction process (with the inevitable backlogs and assuming you get all the paperwork correctly completed first time) - you'd have been up shit creek without a paddle, because you'd spent all the rental income money on your new rental with your partner and all your savings on your maternity leave. You'd have had to go into debt with a credit card etc to pay your mortgage. You put yourself into an extremely vulnerable position in order to rent with him and you don't even seem to realise it.

So far we've got:
Projection
Gaslighting
Coercion
Manipulation
Refusing to pay his way
Sulking
Future faking
Love bombing
Getting angry when things aren't how he wants them
Insulting you
Leaving you to do all the work including for a child that isn't yours
Entitlement
Shutting down reasonable conversation
Classic DARVO tactics

And from you:
Tiptoeing round his emotions
Avoiding saying a straight no to anything
Justifying yourself
Doubting yourself and your reasonableness
Putting yourself into an incredibly vulnerable position financially (renting your house out) and about to do it for a second time (moving him in)
Spending all your savings on this relationship with him (so he didn't have to pay towards maternity leave)
Handing over power for final decisions to him
Selling your house to fund a joint house with him
Letting him mess you around changing plans all over the place and expecting you to accept it
Bending over backwards for someone who's given you nothing but sperm and stress, plus enough smiles and fakery to keep you sort-of-happy and hanging on to the relationship
Altering your behaviour and carefully choosing your words to minimise/avoid the fallout of a negative response from him
Doing all the childcare and housework
Paying more than your fair share

And all this just from one thread. It's like the abusers version of bingo. You're pretty much at a full house with it.

ILoveBrum · 30/06/2025 15:25

Get rid Op - he sounds like a total waste of space. Whatever you do decide, make sure your house is protected.

outerspacepotato · 30/06/2025 16:13

Please don't forget his lack of care for an infant because by having OP do the dropoffs and pickups for his son as well as her daughter the baby was in the car seat for 3 hours a day.

I don't know about there, but here the manufacturer recommendation (and the AAP guideline) is no more than 2 hours per 24 hours.

OP has said she did a couple of DD/DSS school runs a week - it’s not said specifically she did two on the same day.

Still a CF ask from the DP but less of an impact on baby.

That's a good point outerspace. Clear evidence that he's really not a good dad.
