I'm also with Frick on this.. My Agf,now exAgf, hated that I was sober and it drove us apart. She resented the fact that I was not drinking with her any longer. That was 'our thing'..Work, meet at the bar and get drunk..rinse/repeat. She still calls from time to time, drunk.
We project what we don't like about ourselves or our feelings on others. Most of the time the 'others' are the one's we love the most and that's just not good. I know, when I was an active drinker, I took my own problems out on her too so, I can relate.
