Hi OP, just wanted to chime in here as I earn double my husband's wage and have done for some time but don't resent it at all, and haven't even when I haven't enjoyed my job at all (though I do now).
Partly it's because there's no difference in the effort we put in - both have quite high pressure jobs and similar standard hours (though mine it's subject to more intense periods of working late). The salaries are just different because of expectations of our industries so there no shirking to be resentful of!
Second, we always used to organise our finances so that we paid all joint bills proportionally by our take-home pay, after we'd paid for all benefits through our respective work places like pension and life insurance, which always felt fair to both of us. Since having a child, I pay now than this share because it started feeling unfair to me that I had so much more fun money left over than him in real terms and I'd rather is be more equal in that than it always being me buying the treats and days out etc. It helps that he never asked for this and was a bit wary of me doing it because he didn't want me to feel like he was taking advantage. He still refuses to allow us to set it up so that we have exactly the same spending money left over because that feels unfair to him! I respect him being very conscious and appreciative of the fact I bring in a good wage and not taking it for granted that I will just provide, so no resentment there.
Third, I was brought up to always want to be financially independent of a man. That's no judgement on anyone who stays at home because I appreciate it works best well for plenty of people, but it would make me feel incredibly uncomfortable and vulnerable. No comment on the state of my relationship but, because of who I am as a person, I think that the fear would weigh heavily on my marriage. So from that perspective in very comfortable and non-resentful of the situation.
Last, I had a good length maternity leave but still missed my little toddler when he eventually went off to nursery. I think that's natural. He absolutely adores it there, though, and equally loves coming home to us so we have been very lucky and that's made it easier. Much as I adore him, I think I would have struggled being with him 24/7. When I think that we wouldn't have been able to have him socialising with other children during this pandemic otherwise, I thank my lucky stars that he's been going to nursery all this time.
We also have also had a domestic chores mismatch in this house which is now largely solved after a lot of heartache (and I've now made my peace with the night left over!) but I can honestly say that income disparity had never come into it because I am genuinely content with the fairness of how things are set up.
If any of that helps at all!
