I don't usually rant on any social media or public platform but I have to with this to get opinions on what to do.
We are 78 days out from our wedding and just 2 days ago found out that one of the groomsmen might not be able to make it. When we mentioned this to my future MIL, she started giving suggestions and came up with the idea of having my FH's little sister's boyfriend as a groomsmen.
*background story* , my FH and his little sister have not gotten along for the past 10 years because of her nasty attitude. It's been awful to the point that she has treated me poorly and I have never been able to grow a relationship with her. For the past year, the little sister has been dating this guy who is liked by the family but gives a cold shoulder to my FH.
So when my FH tells his mom that he doesn't want the boyfriend as a groomsmen because he doesn't like the boyfriend's attitude with him, his mom flips out and starts talking bad about my brother, one of the other groomsmen, right in-front of me! I couldn't believe his mom has the audacity to constantly bash my FH for his choice on who his groomsmen are. This also isn't the first time she's said comments about my brother being a groomsmen.
*background story* When I moved in with my FH, my brother was hurt, sad, angry about leaving the house and caused for us not to speak for around a year. This also affected any type of relationship growth between my brother and FH. However, we have rekindled our relationship and my FH and brother even hang out now.
This brings me to the conclusion, how do I approach this situation? I don't appreciate her talking about my brother that way at all. I've let it slide other times but I feel at this point, it's so rude to be saying my brother shouldn't be a groomsmen or state how it was a poor choice to have him in the bridal party. I've told my FH it's awful to hear that from his mother, but should I confront her about that or should my FH?
