After 34 years with axh, I wish I respected myself enough not to live my whole marriage with all his lies, one after another. I wish I put my foot down with all his partying when my kids were younger. I think he might have gotten help while kids were in the home and he wanted to be with them. Not sure, as this was God's plan for my families life, not mine.
I don't think I would have listened to my own advice, I loved him (still do). I always felt love could conquer all, but not with an addict. You have to set them free and let them figure it out.
