TLDR: Am I being unreasonable to be really angry about DPs exW lying about her financial situation while we fund her lifestyle and are just living month to month.

Sorry if a bit long as want to give context and not drip feed.
DP split with his ExW just over 6 years ago. We've been together 5. He was in the final stages of sorting his financials in his divorce when we met, I didnt get involved with it but was aware of decisions he was making as he didnt want to hide anything from me. He didnt ask for financial disclosure from her as she pleaded poverty, no savings and tiny pension. He also paid her legal fees as she said she couldnt afford them and he just wanted the whole thing done. He said he trusted what she was saying and also wanted to make sure his child was properly provided for.

Ended up agreeing mescher order until DC is 18 or leaves FTE (4 years time) plus quite a significant number of household bills within the financial agreement plus CMS payments. He also never quibbles if she asks for him to cover school trips, uniform, other ad hoc expenses as he doesnt want DC missing out. DSC says when they ask ExW for things / school trips the answer is we cant afford it.
For context, we have DC every weekend. DP sometimes works up to a 50 hour week. I also work FT around my DC's needs. We're both exhausted and skint with very little time for each other.

ExW works 16 hours a week to get full UC (which she reminds me of at every opportunity if Im the one doing handover, as 'she couldnt work in a stressful job like I do, she just wants to have more free time' (dont we all)).

A year ago my DP moved into my house. He pays half the bills but no rent / contribution to mortgage as Ive made it clear this is my house and I dont want him to have any claim on it if we were to ever split (I had to start from scratch after my split and this house is my security for me and my DC, I cant risk losing our roof over my DC head). He's 100% on board with that but did offer extra money for rent. I said no as hes paying for his mortgage and DC expenses.

End of each month we're just about making ends meet. No meals out, no holidays. We make sure neither of our DC go short on anything though. We have very little savings (I have less than £1000 to my name)

The last year his ExW has been plastering all over socials going out every weekend, weekends away etc. We wondered where the money was coming from and were concerned about her racking up debt that may affect her credit rating and by default my DPs as hes also on the joint mortgage.

A few weeks ago when my DP was collecting DSC, DSC asked him to help look for a school form in a pile of papers on the kitchen table (ExW was out at work). ExW's bank statement was there. She has got £1000's in her account above usual monthly spending / bills.
My DP is really upset and angry that shes been lying about her financial situation while he works to the point hes burnt out and exhausted to make sure she financially has her head above water to support DSC. Hes not said anything to her as he doesnt want to create conflict.

I feel really angry that Im also indirectly subsidising her life by paying the majority for our household to ensure my DP can pay for hers while she works 2 days a week, loads of time off and no stress while I wake up with anxiety every day about my stressful job and paying the bills.
Whenever I see her she takes no hesitation to rub my nose in the fact shes doent work much and how much UC she gets as she cant afford things without it. For context, shes fit and healthy and could work FT if she wanted to. DSC is old enough to be at home on their own for an hour or so after school.

Shes not had any inheritance or windfalls (as she is very vocal about these types of things).

We dont want to let on we know but my DP also thinks she should be offering at the very least to pay back the legal fees he covered for her and hes said he will now refuse requests for money to pay for household things as in her words 'she cant afford it and its for DCs benefit'.

Just so angry and upset that we're budgeting, working hard and going without while it feels shes taken absolute advantage of us and my DPs good nature to allow her to build up savings to our detriment.

What would you do in this situation?

But she never had days out/holidays before being with him. She was struggling before him, she’s struggling now , just slightly less by the sounds of things.

But would she be able to cover half of the costs if he had less outgoings to cover the other half?

For example

OP: Shall we go to the seaside for the weekend I have the £40 to cover half of the costs, do you have £40 for the other half
Partner: No, ex asked for £80 yesterday for new school coats.

If he had split the costs of the coats 50:50 with the ex he would have had £40 of that £80 to put towards a weekend out with her that neither of them could afford on their own.

My mum was on the breadline when she met my dad. He was a low earner but had enough to get by. Together whilst still on a low income they were able to pool funds to allow the odd day out/holiday (weekend in a caravan for example) that neither would have been able to afford individually. My mum was a single parent with zero involvement from the biological father - financial or otherwise. My dad took on my sister as his own and filled in the gap that her biological father left in every way and together they were able to do more for her. Over time they were able to improve their financial position and money was less of a worry but my mum especially is still haunted by those days of being so poor.

We all hope that a relationship will bring us more in life that we manage alone. As it currently stands it isn't for her, I'd give him a chance to review his decisions in light of what he had found out and whether he could shift the dial so they as a couple are not overly disadvantaged in preference of funding the ex wife's lifestyle. He should still absolutely be supporting his children but it's not unreasonable to ask him to reflect whether the support he has been given is still what needs to be given.

Surely it's worth putting this too him before writing off the relationship and returning to a situation where she definitely can not afford her situation, especially as the living costs over the last 5 years have increased disproportionately so what could be afforded on one wage in 2020-2021 is now not feasible

Don’t be silly - she’s allowed up to £15,999

ChalkOutlines · 23/07/2026 13:44

SorrellNightwind · 23/07/2026 12:50

yeah - why is he living there for "free" - he should be paying "rent"

OP doesn’t want him to.

NewGoldFox · 23/07/2026 13:43

Sounds like you’ve made a rod for your own back choosing a life with someone who is divorced and skint. Don’t understand what his ex has to do with it.

Bowies · 23/07/2026 13:42

You are coming across too invested in the financial situation with his ex and quite bitter.

Helpful to detach, even if you are not detaching from the relationship, it’s up to him how he manages things with his ex and DC.

You are self sufficient with your own place.

I don’t think it’s unreasonable that she assumed living together would mean having more spare cash than living separately.

OP needs to:

  1. get him to pay rent as a lodger (which is originally offered, so shouldn’t be a problem)
  2. tell him to stop spending all of his spare cash on extras for his kids (sounds like he’s already onboard)
  3. make a long term plan for when his house is sold
  4. stop engaging with the ex when she’s making smug comments

Needs reporting to UC if she has thousands in the bank.

This.

DrMcDreamier · 23/07/2026 13:41

I’m going to go against the general grain here and say this would massively annoy me. Of course the kids need to be properly looked after and should not be left without, but that isn’t what this is. She is still their parent and should hold responsibility for them and funding their life. The fact he wouldn’t be able to afford somewhere to live without being with you is utterly insane. He should only be giving her what he can afford to, AFTER paying his own expenses. I would tell him to go back to court and adjust things. The cost of living has changed.

ChalkOutlines · 23/07/2026 13:37

Superscientist · 23/07/2026 13:25

By "you" meant her partner/her. Even without fully shared finances if she is having to pay out more for their lifestyle - days out or holidays because he is paying 100% of the extra for his children it impacts her.

He is a parent and he should pay his way, but his children have a mother too so if affordable for both parties the costs of life should have a contribution from both parents. What the respect divide of that cost will be specific to the couple.

But she never had days out/holidays before being with him. She was struggling before him, she’s struggling now , just slightly less by the sounds of things.

Mookie81 · 23/07/2026 09:29

How are you just scraping by if you were paying the mortgage and bills alone and now he lives with you paying half the bills? There's no way him living there drastically ups your bills to the point he costs half of them. So you should still be better off than you were before he moved in. He wants to pay for his kids. As long as he has enough to pay you what he should leave it alone.
Another story of merging households that doesn't work.

Agreed. It doesn’t make sense! If his finances affect you then you should ask him to leave. It’s important he sorted out his first family before making a second. In 4 years those payments will end and he will have more money.

Isitevensummer · 23/07/2026 13:28

She sounds horrible for rubbing your nose in it. It’s not reasonable for him to want money back he already agreed to but he needs to say no in future. As for her privacy- I would have been tempted to photograph her statement. But even without that, he needs to say no, deal with the conflict, offer to have DS if she kicks off, and suggest mediation with full financial disclosure if she makes trouble. I can’t stand women who use their kids to hide behind like this.

The daughter will be adult soon enough. I'd leave it. He soon wont have any financial obligations to the ex. End of. A handful of years really isnt that long. Thw problem will be over before you know it.

Passaggressfedup · 23/07/2026 13:22

A judge can't sign a financial order unless it meets the legal definition of fair and reasonable.

OP is clearly bitter because she thinks the ex has it good when she's struggling. Totally fair enough but she's not looking at the longer picture.

hourspassed · 23/07/2026 13:22

You seem to spend a lot of time talking to her - and this is what's winding you up. Why engage with her so much? Keep it strictly about the DC and don't give her the opportunity to talk about her money. I'd be given her a 'Hi' and 'Bye'.

Your DC should 100% be paying what the court order instructs him to and no more. He can give his DC money for uni directly to them - or pay their rent direct - when the time comes. She does seem to be taking the piss but there is stuff you can do to protect yourself from feeling even more stressed by her behaviour. I'd be taking a massive step back and let DH deal with her.

She's despicable. Typical Mumsnet though OP, it's all your fault and the Dad who's being fleeced.

Bridesmaidorexfriend · 23/07/2026 13:09

yeah I don’t get what the problem is. She’s got savings. Her income hasn’t changed, she’s not hiding a three figure salary. He knows how much he’s giving her and that she’s still entitled to benefits. She’s got a nest egg which is sensible.

If he’s paying £££ more than he can afford then he needs to stop paying the extras. I seriously doubt he’s giving that much or his salary that he can’t afford to live. I think OPs just jealous, which is fine. But that doesn’t mean the ex is the villain

Yeah I can’t see how the DP has been “duped” here.

He knows broadly what his exes income and fixed expenses are. He chose to enable his child and their mother to live well, rather than spending that money on OP. I think that is what smarts, and I don’t blame OP for feeling that way.

However, she is wrong to blame the ex rather than DP.

Im not sure where you're getting your information from re: 'The court will only disagree and look into it if you cant agree and have a hearing.'
Its the complete opposite - Judges can and do still turn something down if its seen as dramatically unfair to one party even if both have signed off on it.
I know three people who've been divorced who were all warned the same during their settlement negotiations, one of whom had theirs turned down and had to go through another step to confirm they were both happy with it, and if you google it you will find plenty of information on how and why it can be turned down.
Is that what your partner told you?

Yes I’ve heard this. Someone agreed to not go after the others pension and the judge wouldn’t sign off on it until he was sure they were actually happy with that as they were disproportionately worse off

Thundertoast · 23/07/2026 13:09

Lovingthesummersun1 · 23/07/2026 12:51

They agreed via solicitor negotiations then it got rubber stamped by the court. The court will only disagree and look into it if you cant agree and have a hearing. I did try to convince him to sell but he wouldn't and thought he was doing the best for his DC. At the time yes, he was spineless. I gave him an ultimatum about our relationship and his spinelessness with his ex and boundaries. Ive shown him since he can be otherwise and hes got much better

It shouldn’t matter how she is doing. He made those agreements with her and they should remain that way. Your finances are your own and that’s where you need to concentrate your efforts. The benefits system isn’t always fair, I was much better off financially as a single parent working part time and claims tax credits than I was in a partnership both working full time. That’s not her fault and she’s not doing anything wrong. Also, every weekend is still not a lot. Your partner should talk to her if he thinks he can’t afford everything but you still have two homes between you so you aren’t doing as bad as you’re making it sound. Perhaps you need to ask him to move out, if you are financially impacted by his decisions. She might be very frugal with food and electricity etc which is obviously her choice and you wouldn’t necessarily know.

Please read the OPs posts. She has explained they were together a year after they split as he was going through the divorce.

So the answer is yes. He was still married.

nc42day · 23/07/2026 13:06

I sense there's more going on here re the financial side of it, to agree to a Mesher order, plus spousal maintenance there must have been a fair amount of surplus income for your DP over and above what was necessary to meet his own housing needs.

Where's that money gone?
