I feel really bad, but I am about as fed up with my MOH as I think I can get. She and I are cousins (neither of us have sisters) who were born 24 days apart from each other. We have always been close (well, up until recently). Two days after I got engaged I went to see her. That day she told me that she was back together with her on-again-off-again bf. From that point on for two months she would not talk to me (she wouldn't answer my phone calls, wouldn't get together with me when I invited her to stuff, ect). Before I moved back to school I called her to see if she wanted to get together before I left. She refused, but her bf informed me that the two had been engaged for two weeks. SHE DIDN'T EVEN TELL ME! My FH and I had set a date for 2011 and she was aware of that. Just the other day I asked her if she had set a date, and she said no but that they were looking at either Jan or July of 2011. I told her that she should pick July because she has always wanted to get married on her family's lakefront property. She said that she was thinking about getting married in Jan so that she could "say she got married before me." I told her it wasn't a race. Today she informed me that they set a date for Jan.
It would be one thing if she was marrying a really great guy. The guy is a real jerk. He treats her awfully, she is always complaining about the way he treats her too. He even has so much disrespect that he told off my grandmother one day! (My grandmother is like the sweetest person in the world. Even if she wasn't, that is not appropriate for a future in-law to do). I can't help but feel like my cousin is marrying this guy because she sees me getting attention and wants some herself (she has always been an attention hog). I am so upset for her for being so inconsiderate and for treating me like dirt. I don't know what to do. Part of me wants to ask her to step down from the wedding party. But I fear that may destroy any shot we have at repairing our relationship. She has asked me to be the MOH in her wedding (I say asked but what she said was "You are going to be the MOH" I haven't exactly said yes to it), and I feel like if I don't it will ruin her wedding (which should be special for her even if she is having it out of spite). I am so torn.
What would you do in this situation? Would you ask her to step out of the wedding party? Would you be her MOH? How would you even approach her awful behavior to me without hurting her feelings or making her hate me?
Any advice would be greatly appreciated.
