Last night FI and I went out to a bar with two of our good friends (a couple). The guy is one of my FI's groomsman and has been our friend for two years and he has been with his girlfriend (a friend of mine I met through groomsman) for a year and a half.
We were hanging out at their house after we left and groomsman pulled me aside and confided in me that he was worried he was sexually inadiquate for his gf. I tried to reassure him that she loved him and I'm sure everything was fine without really getting into specifics (for obvious reasons). I thought the conversation was over and he went to give me a hug, but instead he went in for a full on kiss! I pull back and he went back in a second time! I pushed him away and went to FI and told him we needed to leave immediately.
This morning I got a text from the groomsman. He clearly has no recolection of what happened and then asked me if I would go with him to pick out an engagement ring for his gf. He is planning on proposing in January.
I told FI what happened and he is very upset with groomsman but they haven't spoken yet. What do we do?? Do I go to his girlfriend? Do I say nothing unless something happens again? Do we ask groomsman to not be in the wedding (I know that is generally frowned upon)? I have no idea and this whole situation is totally out of left field and so upsetting. I feel awful.
