I'm in quite the dilemma... My fiance and I have been dating for a little over 4 years. He has a twin brother who has been with a girl for almost 5 years. Over the last 4 years, her and my relationship has been very rocky. Sometimes we're best friends but that is usually only when we have to be around each other. Otherwise, I am constantly hearing from others that she just can't say anything nice about me. Well, just this past year, they ended up getting married and I was the very last bridesmaid. I was even unasked and then asked again to be a bridesmaid after a big fight. She is younger so I largely attribute this to her immaturity but I just don't have the patience to put up with so much drama. So now that it is my wedding, I would love nothing more than to not have to deal with her. But, she is now my fiance's new sister-in-law. So with all of that being said, I just don't know what I should do. She technically is my future husband's SIL and I was in her wedding. I am a very care-free person and she knows that I do not like drama and I will go out of my way to make sure I avoid it at all costs. I don't think it would be a huge surprise to her if I didn't ask but I know she would be infuriated... HELP!!
