Can you go to your embassy & go back to your family with your son?

I would probably start with that. Distancing from the hurt where you have support really helps. I left & moved to a place where I knew no one but made more wonderful friends than ever before in my life.

I would also talk with a lawyer. They may suggest you leave the country with your son & file for divorce in the country you are from. Some divorces otherwise require the child to star in the state the divorce happens in.....good to get legal advice on this
