I've already chosen my MOH & 3 of my BM's, and I'm facing some indecision about my 5th girl. My sister is my MOH and my 3 BM's are my stepsister and 2 of my childhood friends. My FI has his heart set on having 5 GM, so I do need a 5th BM because I want my wedding party to be balanced. I'm trying to decide between 2 girls: my cousin & the GF of one of my FI's GM. I'm not very close with my cousin at all, she's a bit older than me, but I was thinking about asking her because she's family and my grandma suggested it to me because it would mean a lot to her. On the other hand, my FI & I are close with this GM & his GF. I'm not exactly best friends with her because they live far away & I don't get to hang out with her a lot, but I really like her. My FI mentioned that it would mean a lot to both him & the GM if they got to be together at the wedding, and I'm not against having her in my wedding at all. Plus, she told me that when they get married she wants both me & my FI in their wedding so that we don't have to be separated. I don't have anyone else I want in the wedding because I don't have a lot of girlfriends, so I can't just resolve the issue by choosing neither. What to do??
