I agree 100% with NNP and Jill and wanted to write it last night but you usually get very upset at my blunt posts. Now I see that you are writing EXACTLY what I've been saying all along. But girl - you have to stop writing about it. I've been telling you to dump his sorry ass for 2.5 years but seriously - I think you are afraid to be alone so you'd rather hold on to a loser than have no one. JUST DO IT! What are you waiting for. You are getting older and your biological clock is running out with someone you would NEVER want to have a child with. Stop wasting your time.
My advice today is the same as it was 2.5 years ago. MOVE ON! I have been divorced about the same amount of time as you. Can't even remember the month never mind the date. I remember what my anniversary was but don't dwell on it. I don't dread it I usually do something fun that day. And I was married to him for 25 years with 3 kids.
Your friend who emailed you is a good friend. Because good people will tell you the truth whether you like it or not. I'd like to think that I'm one who cares and I'm beginning to think you're gonna figure that out.
