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.

Yes, I used savings to cover my wage for 12 months- they just about got me to the end- I have no more savings now

Gasp!!! 🚩🚩🚩
Seriously, while you were on maternity carrying HIS child, he didn't support you???

And you do know that the 50/50 on rent isn't fair don't you - not if you do the lions share of parenting and home-making? If you take that on then you should see the financial benefits.

To answer your question about your DSS, no you're not being unreasonable at all in expecting him to use the small bedroom. Even your thread title is misleading - you ARE providing him with a room. As the youngest he gets the smallest room, that's how these things work.

But this issue really isn't about the DSS, I think you are focusing on the wrong thing. It's about your partner's inability (refusal?) to take his share of the financial load in this relationship. I know you don't want to hear this, but if he won't step up and start paying his way fairly then you need to reconsider the relationship. Unless you are prepared to keep carrying him indefinitely.

And when the OP tries to discuss money, he accuses her of being “all about the money” …

Mind you, my ex was genuinely baffled how I was going to meet my half-share of the household bills iIf I ever had a child. My Dad had no problem with supporting my Mum (and me and my brother), it was just the done thing. So what the hell happened?

Greenvases · 30/06/2025 18:08

" Until I put my foot down recently I was also running around like a blue arsed fly doing two separate school runs a day so that I could collect his son, then making tea and providing childcare until he got back from work."

The OP quite clearly states two trips a day in the car for 90 minutes with a newborn.

An awful thing to do to a newborn.
She clearly puts this man ahead of both children and herself.

He is not a good father.
He's a user loser who has deliberately had her use all her savings on mat leave.

Him and his ex use her, she pays more than her share, so he can be the big man.

She knows well this is very wrong, hence why she misleads people that he is supporting her financially during mat leave.

All the while saying her daughter is unaffected.
The OP is extremely vulnerable to this user loser, so is her daughter.

At least her daughter has a decent father.
Of the two men I would take her ex husband any day.

Scarlettpixie · 30/06/2025 18:15

I think if you want to live together, then going back to plan A with your daughter in the bigger room, DSS in the smaller room and the baby in with you seems like the best solution. Then work on doing the conversion or moving (which ever you decide) so that they can all have their own rooms. Or how would your daughter feel about sharing with baby in her room. Is that an option - especially if not meant to be long term (so by the time she is 13-14 she will have her own room again). If you do the garage conversion, get it done professionally as it will have to comply with building regs. I had our double garage done a few years ago and it was cheaper than I expected and only took 2 weeks (we had the garage doors out and windows put in). I understand he has messed you about by saying he will move out and changing his mind but you can't really penalise his son who deserves to have some space of his own and be in a proper bed. You are either a blended family or you aren't. .

SheilaFentiman · 30/06/2025 18:16

@Greenvases and in another post the OP also clearly states:

This was only possible by me doing a couple of school runs a week and providing childcare during school hols (I’m a teacher)

So… we are both picking up on a different post!

SereneHare · 30/06/2025 18:35

he’d be furious to know that I used my savings for maternity.

There's a reason he'd be furious.
There's a reason you didn't tell him.

Because it's not right. You know this deep down OP ❤

Your ExH would also be furious that a scrounging cocklodger is jeopardising his daughters security. If you can't leave for yourself, for her sake, please get out of this.

If I separated from him ........ my exH would up my spousal maintenance so that daughter and I could live comfortably

You obviously got divorced for a reason. We don't need to know but your ExH cares more about your financial security than your current partner.

DP always comments that ‘it’s ok for you because ExH will just come to the rescue’

Good, because this twat won't.

Oh OP. What more is there to say ❤

@Scarlettpixie the DSS has always been offered a room, just not the biggest room. He was offered a smaller bedroom, the OP wasn’t expecting him to sleep in the shed!

She literally says in her OP:

This would leave DSS with no bedroom.

She decided on this plan AFTER the DP said he wanted DSS and baby to share Dd’s old room and, if not, he would get a separate place.

ReadingSoManyThreads · 30/06/2025 19:18

Just read all of your updates from yesterday. I would honestly end it with this guy. I think any man who makes the mother of his child pay 50% of all bills/rent/mortgages etc., whilst she's not earning on maternity leave, are LOW.

I'm furious at your DP for that. Honestly, the way he speak to you when you raise the unfairness of finances - he comes across as very snidey and manipulative.

I honestly think you'd be better ending your relationship. Move back to your house and claim CMS from him. I'd honestly be honest with your exH on what a financially irresponsible user your ex DP was.

changeme4this · 30/06/2025 20:10

Please go back to your own place and he finds accommodation elsewhere with his son for now.

the couple who I mentioned up thread as separating never addressed the imbalance of contributions/assets during the course of the relationship, Despite working and having considerable disposable income (Ie wasn’t a saver but spender) one partner didn’t build a nest egg.

now they have separated, she wants the settlement divided that he retains the pre marital assets and she retains all of their joint marital asset (the home they bought jointly and renovated jointly). In a nutshell he sees nothing of his share of the home equity.

similar situation to you.

Evan456 · 01/07/2025 16:20

How old is your daughter?

SheilaFentiman · 01/07/2025 16:40

Evan456 · 01/07/2025 16:20

How old is your daughter?

DD is 13, DSS is 11. It’s in OP’s posts.

Isthisit22 · 01/07/2025 17:04

How did the talk go? @Moorside111

Evan456 · 01/07/2025 19:23

SheilaFentiman · 01/07/2025 16:40

She should have her own room at that age

SheilaFentiman · 01/07/2025 19:35

Evan456 · 01/07/2025 19:23

She should have her own room at that age

Wow, that is brand new information…

We are on p24 of the thread and I don’t think anyone has suggested that DD doesn’t have her own room. But if you read it, you can have your questions answered and maybe prove me wrong.

FeistyCat · 02/07/2025 07:05

How did it go @Moorside111 ? Sorry but I think he's a cocklodger. He blew through all his money knowing he could bludge on you, and that you had a separate home. A home, a cook, laundry, a child carer; he saw you coming imo.

chaosmaker · 02/07/2025 23:11

Hope you haven't let him move into yours @Moorside111

Christmaschildcare · 05/07/2025 16:14

How are things @Moorside111 x
