Wendylon, I agree that the DB coaches are great and much better than any IC or MC.
His reaction about the party is bc of the mental image he has of you. If you feel strong enough to do it, give it a try and just relax and have fun even if you don't drink. Your H will see he can have fun with you at a party. Try to change the old behaviors/habits. My H and I don't drink either, and realized it doesn't really matter. You can still have a good time. I just went to a beer tasting party and didn't touch the beer :-)
