My ex wanted to cut me off from everyone I knew before I met her, especially my fambly.
DiL will be the one to ultimately pay for the things she is doing now. She has a son who is 11, and she is very close to him. I hope I live long enough to see what goes around comes around, but one thing I know for sure: It eventually WILL.
I would pity her but it would seem her machinations are deliberate, not unconscious.
