I'm going to tell my fiance I don't want her male friend in our wedding
Why don't you want your fiancee's male friend at your wedding?
He is way too friendly towards her.
Maybe that's just how he is. Maybe it's too soon to jump to conclusions. Heck, he might actually be into men. You never know. It's best to just get to know him better. There is a saying, "Keep your friends close, but keep your enemies closer."
I also don't like his tie, it makes him look stupid.
Well he obviously isn't winning any points with you. If your wife enjoys his company, then you should try to get along with him for the wedding. I'm sure it would mean a lot to her if you could put your differences aside for now.
