Dave & Me - it is coming to a close now.

After all the soul searching, really liking and respecting myself, I have decided that I will be breaking up with Dave.  I don't know when or how I am going to do it but enough is enough.  Dave criticizes me and is surprised that I get mad at him.  Dave is an alcoholic who drinks and drives.  I don't need that crap in my life anymore.  I want a good person who drinks socially and is responsible about it as well.  I want someone much better than Dave.  I really lowered my standards when Smokey died but now my standards are back again.  I think I am trying to be an honest and genuine "me" again.  I think I am coming back after the almost two years in November pain of losing the love of my life Smokey.  I know Smokey would want me to be with a decent guy, which is not Dave.  Dave has a kind, caring, genuine and loving personality.  Its why I have been with him for so long.  The two negative things about Dave have destroyed our relationship.  There is no mending fences.  I guess I see things in black and white.  If anyone sees my relationship with Dave in a different light, I would really like to know.
