Deesire,
Welcome. I could have written most of your post. I divorced my AH earlier this year. I maintained no contact for a while and now have limited contact with him. He is attempting recovery but just as it was during our marriage hasn't maintained it for any length of time. I realize that I need to go no contact because his disease is still affecting me. He simply "drops off of the radar" and I always fear the worst.
This forum and AlAnon are the best things that I could have done.
