This is clearly a very tricky situation and needs to be handled with kid gloves. Here, how 7 real brides handled this uncomfortable scenario.
"My fiancé's college roommate, whom I'd never met, came for a visit around four months before the wedding. Ironically he was with his fiancé. I was in the kitchen putting finishing touches to dinner and this joker came in and grabbed my butt while asking if there was anything he could help me with! I was nauseated but said nothing till my fiancé Dan and I were alone. Thankfully Dan immediately disinvited his friend to our wedding." —Sara
"Five years later I still get nightmares. At the rehearsal dinner my fiancé's best friend who I'd known for years got rip roaring drunk — understandable since his longtime girlfriend had just broken up with him. He grabs me in a corner and plants one on my lips. I slapped him and ran back to the party. The next day at the wedding he didn't even remember it happened. So I never said anything — this is my fiancé's BEST friend — but still cringe a little when he's around."—Diane
"I told my fiancé the second his scuzzy friend — actually, second cousin — came on to me. My fiancé actually went and punched him out! I felt very taken care of and more in love than ever." —Tami

"My fiancé's friend made sexually suggestive remarks to me at a barbecue. I called him on it, saying: 'Do you want to tell Eddie (my fiancé) or should I?' He turned beet red and said, 'I'm so sorry. It will never happen again.' And it hasn't!"—Kim
"My fiancé invited an old friend of his over whom I'd never met. So this old friend turned out to be an ex of mine. I was so shocked I didn't say anything when we were 'introduced' and neither did he. The next day he texted me to ask me out for a drink. That's when I fessed up to my fiancé. I didn't want to start our marriage off with lies or pretense." —Beth
"My fiancé's childhood friend who is gay said that if I was gay and not engaged to her good buddy she would be sooo interested. And had I ever been with a woman?' I said, 'That is a lovely compliment and no I haven't been with a woman.' I also told her which is true, that I'm happy in my relationship but if I was gay she would definitely be on my radar!'" —Cara
"When my fiancé's friend asked me if I wanted to meet him sometime for a drink I said, 'I am going to pretend you never said that and you do the same thing or I will tell my fiancé and you will be toast.' He slunk away and has never bothered me again." —Nina
