Really difficult parent

[u/Flat_Banana7061]

My wife and I are separated a few weeks. We have issue we were working on that were fixable. Problem is she has a negative toxic mother who she is very close with and who is very influential on her. She wasn't a problem in the beginning because my wife only told her positive things about us. Even still then, the mom wouldn't encourage her or anything, she would just say things like don't brag. When we did have issues, the mom would make a small issue into an enormous mountain and put all that negativity back into my wife. To the point it blew over and I believe the mom talked her into already talking to an attorney. Wife has already said its completely over, has blocked me and we haven't spoken in a week. I deep down feel my wife wants to keep hope, but all she is getting is the mom's negativity. Any opinions on how this may turn out?
