Hi,
I can relate to all your feelings. I am doing okay now... I am still angry too, however. Angry at him, angry at myself and angry at alcohol for ruining our relationship. Somehow it seems like anger is the most difficult thing to let go of.
I think sometimes when you've been in a bad relationship for a while, you do a lot of your grieving while you're actually in the relationship realizing how much things are starting to suck and the fact that they'll never work out, know what I mean?
I wouldn't worry about going through the grief stages too quickly, I think everyone goes at their own pace.
