Ever since we were children, it's been known that my cousin (who is more like a little sister to me) was going to be my MOH. I recently got engaged and informed her I was going to keep that promise. However, as soon as I told her my vision for the my wedding she began to bug me. First, she believes I'm waiting too long to get married (Mar. 2014) and that I should have it this year (my fiance and I have plans to save up enough money and will not be able to afford it until late next year, but I want a spring wedding). When I explained why that wasnt possible, she began to say that she doesn't know if she'll be living around here then (third time she visited a city and HAS to live there now). Then there is the issue of the dresses....she thinks that i should allow her to wear a low cut mini dress because she wants to look sexy and stand out. I told her no, firstly because this is a wedding not a night out at the club and secondly because it's my day and I don't want everyone staring at her in a shocking dress instead of watching the ceremony. She told me anything else would make her look ridiculous. Also, my fiance has only twenty people to invite and my family is so large I had to cut family members (only the ones I rarely see and never come to anything else I've invited them to) and some friends so it wouldnt be too unbalanced or expensive. When I told her that, and also that we planned on only having family members over the age of 21 at the reception she freaked out telling me who I HAD to invite including my twin 16 yr old second cousins (who never talk to me even when I say hello), my 12 yr old cousin who I never see, and the mother of the twins and her boyfriend(she is also my cousin, cannot hold herself together when she drinks and has the police called to her house almost every weekend because of that fact). When I put my foot down and said no she called me a b*tch. She also said she won't have time to help me at all because she's always so busy (she works 3 nights a week and parties every day she isn't working). At the same time, I have a friend I have known since 3rd grade who jumped in to help me out with everything without being asked because she said she had gotten stressed out planning her own and doesn't want the same happening to me. What I don't know is do I keep my cousin, who I promised so many years ago, as my MOH or tell her nevermind and have my long time friend instead.
