Q: For the most part, things seem pretty good between my girlfriend and me. But give her a few drinks at a dinner party, and the zingers start to fly—always in front of our friends. Last month she “joked” about my taste in movies and just the other night she made a very nasty remark about me not doing my share of housework. The next day, I usually confront her about it, but the discussion turns into a “You were nasty/No I wasn’t” one instead of a “Let’s deal with the underlying issue” one. What do I do?
