Yikes! Buttercup! I'm sorry about your wedding! Yay for second chances though.
My gbf(gay best friend-my man of honor) always does the defending for me because anger is not my strong point. Plus, like you guys, reiterates that it's my day and that the girls are just being awful people so they don't deserve to be my friends.
Mother-in-laws are scary. My fiance and his best friends all think my future mother in awesome and really cool, but I get bad vibes from her, like she doesn't like me. When we got engaged she wasn't very pleased. She's always cordial, but it's that kind of nice that doesn't really ring true.
