So I've read most of the posts and am trying to wrap my head around the situation.
Honestly, there are plenty of other fish in the sea. You can find yourself someone who loves, appreciates you and doesnt see you as a ATM or think that all the extra money you guys have should be sent to her family.
Life is too short to live it unhappy or with someone who doesnt appreciate you.
If she doesnt understand everything you have told her, and tells you that you are cheap, it sort of sounds like she is not mentally ready for a marriage and to take on what comes with it. The actions you said she has displayed with making life miserable or acting badly because you cant send her family all your money honestly is childish sounding.
Sending $100-$300 home to her parents is about the farthest I would ever think of going and I would be damned if that was expected of me.
I hope your situation gets better, but honestly, if I were you. I would divorce her. People dont change, very rarely they will, but dont bank on it.
