I feel your pain. I've been with my wife since we were teens. 21 years now, 4 kids....and I'm divorcing her in the new year. As with you, she isn't a person I know. She has hurt me beyond imagine. Cheated on me. I don't know who she is.
I suppose my point to you is. It's so outside your control. I have 21 years and 4 kids to convince my wife to try....and she won't.
If I only had a year, no kids.....I'd have run long ago.
