Doesn't sound like much of a friend at all. I'm two weeks sober tomorrow and I've e-mailed/talked face to face with a few of my 'drinking friends' and told them what was up. Not one of my friends has so far said anything negative, it's all support and I guess I'm lucky in that sense. I guess it also shows how outwardly apparent my alcoholism was!
But I've been up front about the fact that if anyone has a problem with me not drinking then I'm going to have to let them go from my life.. Which was a hard thing to do because I didn't want to end up friendless and have to start over, but I had to accept that if that's what it came to then I would just have to try and make new friends who would appreciate me for who I am, not for the mask I wear when I'm drinking. Plus I'm actually 100% more fun when sober, or maybe just 100% less fun when drunk :P
Welcome to the forums, hope you stick around!
