My wedding is in a few months and it was obvious who my fiance's best man would be. I'm close with him as well, so I was fine with it, until he recently cheated on his wife. Rationally, there is no one better to be best man, but the thought of this guy, planning the bachelor party and what not makes me anxious... I feel like what he's done is the opposite of what marriage stands for. He really disgusts me, and thinking of him up there with us just makes me uncomfortable. However, I don't want to be a control freak and tell my fiance to choose a new best man. Any suggestions or thoughts?
