In a nutshell,
My fiance and I are going to a birthday dinner this Friday for his best friend - and who will be the best man at our upcoming wedding. The issue is his best-friends wife's sister will also be at this dinner. She is a leggy, blond (very attractive and knows it) and has always been interested in my fiance. She goes out of her way to touch, hug, be near (WHATEVER SHE CAN) my fiance.
He says I'm over reacting. She is just friendly and trying to be nice. He is being very naive or doesn't want to upset me.
I need some advice from anyone - for this upcoming friday night. I don't want to appear to be insecure or a b*tch - but I really am nauseous thinking about all the scenarios that could play out this friday.
Help!
