You say "limiting DD's future prospects" what does that mean in your thoughts?
A happy, relaxed mum who has time to discuss books, school work, enjoys taking them to activities or days out with happiness is far, far, far more beneficial for "future prospects" than what, bigger house, the best clothing, an expensive but essentially hollow holiday abroad with two parents who dislike each other.
Don't get caught up in tick boxes, that you need this, this, this and this, a really nice car to pull up at sports day. It doesn't matter. None of it.
Having a dad who hasn't got contempt for her gender will empower her much more.
We have boys but they have a dad who said yesterday, in light of the talk of misogyny being discussed as a form of terrorism, "how can someone just decide to hate half the people", he works in a sausage fest industry and when a female turns up he breathes out because it makes it all much less of a sausage fest which is better.
Materialistically we have very little to view, but we have two growing into confident, respectful, socially and emotionally intelligent and are able to come to us with anything, either of us. A considerable influence on why they are developing into amazing rounded human beings is the positive influence from both me but their dad particularly as well.
Children from the age of 6 look towards their gender parent for guidance, so think about things OP. What are you and her dad teaching DD? What are her influences of expected behaviour in romantic relationships moulding into? Are you a strong, independent, listened to woman, with views your partner respects? Do you play games and make excuses with PMT or allow gaslighting over housework and put yourself as a female bottom of the heap?
You have the ability to change things, it might be a sideways or downward move at first but in the long game is that such a bad thing?
