(((((Monty))))),
You are so strong.
My abusive mother live with me & drive me, h, & kids mad, until she died at 96 years of age. She hated me I think. She wanted to ruin my life because she perceived her life as ruined.
She only died in 2003 at Easter. She hated me because I was a bastard I think, but she must have always known I would be, as my father was married to a woman who wouldn't divorce him. Dad had been dead over 30 years before I found this out.
Be strong, don't let her get to you. Have you got siblings who could share the load ? I didn't.
Protect yourself !!! Her problems are her problems, not yours.
