A few weeks ago we had people over before an event. This guy named Paul and his girlfriend basically invited themselves over. Later in the evening, Paul comes up to me, grabs my arm, and yells at me that he is so pissed off that he didn't get invited to our wedding. I tried being nice about it by saying that our venue was small but what I really wanted to say was "I don't even know you and you are a complete drunk and a loser so why would I invite you to our wedding!"Fi came up when he saw what was happening and let him have it and we left.Fast forward to this weekend and Paul shows up uninvited once again to our friends' housewarming party. While I attempted to avoid him, fi made him apologize to me. He came up to give some half-*ssed apology and then denied ever getting in my face. He even told everybody that fi and I left the previous event because fi and I had gotten in a fight. Now I don't want to hang out with fi's high school friends any more because I'm afraid this jerk is going to be there. Would it be wrong if I just stopped going places where this guy was going to show up?
