Marie, could you possibly get into a shelter until you are safer? Or get to another State away from him and cut contact? my dad was also miserable to his mom... she always said it didn't matter, that they were jst pin pricks. i told her a person can (metaphorically here) die from too many pin pricks. she never did anything about it. it was just our lives, too.
I hope you can have courage and stand up for yourself.
Hugs, Kiya
