You're one man. Not all male teachers.

Not to discredit your lived reality, but whether or not one is happily married is not contingent upon one's profession. There's no reason to think that just because your marriage is an unhappy one, that all male married teachers are unhappily married.

For what it's worth, theoughout my educational.years, I had maybe 20 male teachers. One, that I know of, was gay and also a screaming misogynist, around 10 were married, that I know of. Seven of those had to have had a happy enough marriage (at the time I knew them) because they were genuinely, outwardly, happy people and you know what they say, "happy wife, happy life". Well, the reverse of that is true too, and for the most part. Two more, things were said during lesson, lab, school trip, and observed on school trip because sometimes the wife came with as a class chaperone (free ticket and sorta date just for doing a head count and riding the bus - can't beat that), or after school acrivities that made it clear they were happily married. The others, I haven't got the faintest clue, and as a student, it wasn't my business.

My uncle was a male teacher (retired now) and he was happily married. My aunt wasn't, though, and they eventually separated. Her unhappiness stems from the same place yours does. He never respected her, never valued her, was cold and dismissive, unaffectionate. He married her for selfish reasons, based on Southern Baptist beliefs.

I hope you can get out of your marriage like my aunt did. The kids won't be young forever. You can work your way out of financial comstraints. It'll take time. I get your reasons for staying.
