Sorry to hear your story. How long did you end up standing before you realized there was no hope for him? I hope that if you have kids, they are ok. My kids are quite young for my age. They have no idea because we play nice. I am so worried about them, as they are very close to both of us. My oldest will never recover.
That is said that your X lost his wife. I am sure that sent him further into the tail spin. Are you dating or did he destroy everything for you?
It sounds like you are real put together after the hell that you have been thru. You are quite strong, and I hope someday I a can be half as strong as you.
