Thanks everyone, some eye-opening perspectives here. Agree that he sees me as lower-earning when I could earn more, but his body also did not have to go through what I went through, so a change in jobs would tip me over the edge - it isn't just about money.
To give more context to this, I did change jobs twice in the last 3 years to earn c15k more than I am now but was extremely unhappy. I get alot of freedom and flexibility which has now come in so handy around our daughter which is vital when we have no family around (e.g. she was off sick with ear infection then chickenpox for 3 weeks when I first went back to work, and guess who stayed off). This was because he had to take unpaid parental leave, and I was luckily still paid (even though he can more than comfortable afford to take it).
This is why these things are so complex as there's many many things that make up the whole picture. For me it comes down to the way he's making me feel - as if I'm some sponge trying to take his money and 'wouldn't survive' without him. When I've proven a good hardworking partner who's self-sufficient already and capable of giving my share, and deserves to be supported in these early-stage moments.
But now we have her, and she's so young, this IS the best job and it isn't just for her, I love my job and team and am genuinely happy, that should account for something as if I were stressed it would affect the family so the stress appears in other ways.
Yes, my lifestyle is likely above my means, but he will not let me pay less on the mortgage because 'its not what we originally agreed' and is desperate to keep it all 50/50, so am kind of forced to keep paying a crazy amount to try and pay it off in 10 years, falling further and further into debt and taking 2nd jobs here and there (and have done for 5 years).
Sure I could spend less on takeaways etc and maybe that's where I could help myself. But I am resentful because I've given 10 years at 50/50 when he is the higher earner and never said a word, and now he earns double and CAN help, It's like he's withholding that to 'teach me a lesson' when it's simply not true, I just couldn't mentally handle changing jobs again at the moment as a new 1st time Mum with a 1 year old baby.
And part of me is angry I'm being made to feel like I have to when I'm finally happy, 33k isn't low-paid in my eyes, and we should feel lucky I'm getting that - I've gone straight back to work full-time instead of part-time which almost all women in my circle certainly have not done.
To add, I did want to go back part-time for 6 months but sadly he refused to let me put down the mortgage payments to do this and said 8 months was already enough off so I would have to pay for it (knowing I didn't have the money and he got a total of £115k with bonuses last year). Grrr again this builds resentment because I'm losing valuable time with our daughter and would save him money on nursery costs too.
I wouldn't lead this lifestyle if I was on my own obviously, and I have shown more than capable of being able to provide so actually he isn't teaching me anything, so disagree with that opinion completely. I also now understand a bit more why the higher earner should contribute more - because he has more disposable income he's more likely to spend more freely on shopping, dinners out etc, pushing the budget up even further that I'm expected to pay 50/50 on and have done for 10 years.
I am from a low-income background and know how to live more frugally but it's so hard when you live / have a partner who earns more and you get worn down from having to penny-pinch every single meal and every single big shop, so you just end up going along with it after a while.
A small glimmer of hope, he has offered to pay £200 extra into the variable join account we have (for food, petrol, takeaways, leisure etc.) but only on the condition I still pay the same on the mortgage and fixed costs (e.g. childcare). This isn't ideal as the whole point is for me to pay less and think that the money will just get wasted, and I argued and argued that why couldn't this same £200 be put to better use towards fixed costs, but he felt 'unsafe' doing that whatever that means.. and now because he's lost my trust, I don't believe he won't take it away. However it is a step in the right direction. Eugh.
should I still be paying 50/50 on the monthly mortgage payments if he owns 64% and I own 36% thought? So confused.
Wow that was a long post :)
