I started this in AIBU, but realised it is far more complex.
Our DS's (8 and 4) go to a lovely private school near us. DS1 has been there since nursery, DS2 at nursery there, due to start reception in September. They are both really happy there and doing very well. I have no strong feelings on private/state, but realistically, I can see that what they get (for instance DS2 will be in a class of 14 max), DS1 is sports mad, just isn't offered in state schools. DS1 went there because it fitted in well with my work, the opportunities it offered were great, and tbh, DP wasn't that interested in schools, so left it up to me.
Since then, DP has decided that he doesn't agree with the 'principle' of private schools on the basis that if the state is offering you something for free, you shouldn't then pay again. Against my wishes, he applied for a state school place for DS2. Obviously offer day is tomorrow.
The fees were just about manageable, until my parents (who are well off, but not uber-wealthy) set up a trust fund, which will pay half the fees. I will pay the remainder.
We have reached an utter stalemate, to the point that our whole relationship has deteriorated. I don't see why our DS's should have to change school just because of some issue DP has with private schools (and he's a bloody Tory voter...) that he can't even explain to me beyond saying "I just don't agree with them".
DP says that I have control issues. There is a lot about him that I love, but his issues are far deeper than this. We both work full time in the public sector, I am slightly more senior (and earn more) than him. I do the majority of the childcare, housework, general day to day organisation, although at his instigation we have an au pair (his idea, but I had to manage it all) which is a great help. We have a small mortage on a lovely house, nice holidays, good friends...
I know he had a pretty miserable childhood. His siblings between them have multiple marriages and children, as does his mother. His father is dead, although he had no contact after he was 5. He is on a low dose AD. I suspect he feels guilty. He never feels contented...always looking for a different job/house/car. I think the school thing is a red herring, not sure where to go from here. He suggested counselling, which I agreed to, on the condition that he organised it. He has done nothing about it.
