Thank you for taking the time to respond. All advice is helpful. Even if I walk away with just a bit more insight than I had.
My parents are deceased. I have three dogs and a cat. I know from past history that they would not be taken care of if I left them here. My best friend lives two doors down so that would be weird. Not to mention that my daughter is living here. I could never leave her here alone. Therefore, she would have to go with me.
He has made sincere efforts before. More than I care to count or remember. He has absolutely no intention, or interest, in ever seeking treatment. He will never ask anyone for help. The last time it got ugly here, I begged him to see a therapist/counselor. He said I could be his counselor. I drew the line with that. I don't want to sever all ties with him. But am I willing to leave? Yes. Just terrified to do it.
