It’s over.
If you can rescind anything rescind it.
Gather evidence and have a dash cam / nanny cam / whatever.
Never lose your temper and every time she does keep a journal
Be the first to file for protection order as soon as she does anything like throw things break things, block you in when you try to leave, electronic surveillance against you. Call the police and get a police report or two to back up your case.
when you are ready file for divorce and don’t Warn her about it just have the papers served.
Protect yourself above all. She could put you in jail and take everything if you don’t protect yourself.
But get it completely through your head that it is over.
It's only fraud if there was intent. If somebody goes on a vacation with no intent to marry, then serendipitously meets and marries the love of their life, that's not fraud and it's a legit path for adjustment of status. Granted there will be tons of scrutiny but it's not automatically fraud.
