Being the sober guy at parties is the bees knees. I had some mates in the Army that were well advanced into their martial arts and never drunk but were the life of the party. They were just sociable, confident, happy guys. They drew people to them, the girls loved them and they were sensible when things went silly like during a altercation. Meanwhile I would embarrass them with the things I said and did as I staggered about being being a loser.
I could not imagine what it would be like being in a relationship with someone who gets wasted while you are tying to stay sober, that would be very hard. Despite your situation work wise and personally I reckon that you are on a good thing while you are sober. I remind myself every day that if I lost everything because of reasons outside my control it would be my choice to the bitter end whether to stay sober or not. Its the only thing I can control and while I'm sober life seems to be working out as it should.
