I have four bridesmaids slots ( for lack of better word) One (Sarah) dropped out because she is pregnant and due on my wedding day. She started to be whinny so I was quite happy. So Tina asked to be my BM and said she was offended that I did not ask her before I asked Sarah, because I coordinated , planned and did so much for her wedding. I thought because she was having money troubles ( her husband not working, new house, new baby) and she has not been around much she would not want to be a BM. Out of frustration I said fine be a BM, I regretted saying yes. A week later she tells me she does not like my FI and thinks our relationship is “fake”. My responce wasI said oh since you think our relationship is fake and Sarah’s BF is not driving and Sarah has no mom why don’t you drop out of being a BM and be there for Sarah and her pregnancy. Tina said well Sarah is not going to have the baby on her due date that never happens and if she does I will just leave your wedding early. My thing is if you do not like my FI and you can not really be there for me then don’t. Since I do not have help from my mom I really need my BM. I do not know why but I have a friend who has been supported loves my FI and I should of asked her first but I did not Tina could be replaced and / or I do not mind having an odd number of BM to GM/ I just do not want someone who does not support my relationship to be a BM. Any advice.
