Your story breaks my heart. I don't know whether she is this way due to a cultural difference, or if she is just this way and would be this way if she was from the USA. It sounds like you feel responsible for her, yet at the same time, the relationship is not healthy at all. You are visibly suffering.

I guess a good question for yourself would be: If I divorced her, could I really let go? As it is, you worry about her being out all night, you worry about her not being able to support herself even if she had enough money, and you seem to feel very responsible for her. Could you let go if she was out of sight and moved away?

I wonder if there is a support group for you, even if it's online. Sometimes, if you read what others go through, especially if it resonates with what you have gone through, you are better able to empathize with yourself. I feel like you have trouble validating and empathizing with what YOU are going through, and have been through.

You have done so much for her, and yet it clearly isn't going well. You are to the point of physically suffering and damaging yourself. Please talk to a lawyer about how you could settle things in a way that would keep you safe and healthy. I think you matter. I want you to think that you matter, too. Keep us posted. We care about you here!
