ButifulDreamer,
It's an incredibly brave thing you did. I greatly admire your courage. I'm not in your situation and never have been. I'm the one whose drinking has caused destruction and pain. You can't share someone with alcohol and be happy and it sounds like he had a long time to deal with it. His new relationship will be ruined by it too, perhaps not straight away, but it will.
And hey, it's not about what the new woman has and what you don't. It's about what you have that she doesn't. Which is knowledge, guts and self respect. My heart goes out to you.
