My F's Bro is married. I was not planning on having her as a BM. His parents are shocked and have been bugging him about it and he asked me to reconsider. We don't hate each other but we are not extremely close either. I just want my closest friends and my sister there. I'm having 6 bridesmaids and he is have 11 groomsmen. He couldn't pick between his closest friends so I let him have 11. I have not forced him to include any of my family members in his wedding party (cause there is 1 in particular that he does not get along with). So I feel that I should not be force to have someone that I'm not close with as a BM. Especially someone who is not a blood sister to him. I am willing to have her do a reading but I don't know if that's good enough for my FILs. Am I being unreasonable? Our fight has become "an eye for and eye, a tooth for a tooth" type of fight.
