Hey OP,
I dont know if youre still reading this since it turned into a childish battlefield, but I thought perhaps since your wife refused to get help and been threatening you that she's leaving, maybe actually just LEAVE. Not permanently but just a cooldown period may be able to solve the problems. I know there's immigration law and all that but at this point it doesnt matter. Save your marriage first. I suspect that she's doing all these because she's convinced that you cant leave her however bad she is and that's why she can threaten you with leaving. So you can show her that yes, you can and you will. Stop arguing or responding to her nonsense. Pack your things and get your flight ticket. Tell her that you will not come back and if she still cares and loves you she will decide to change and she can come find you in the US. Dont go to her country again to put yourself under her power. And if she will not change, consider it your vocation to live in celibacy and repentance from then on.
God bless you.
BTW Just curious, unless Im missing something, is she vaxxed? Because I remember the immigration law required all foreign spouses to be vaxxed to apply for residency. Did they change that?
