Awhile ago FI and I told his mom that we were thinking of having his nephew "P" in our wedding as RB. However, FI had 4 nephews and I have 1 so we hadn't finalized anything yet. Well this weekend FBIL (P's dad) mentioned something about a tux for P for the wedding. And I'm sitting there thinking "WTH?? We haven't even asked them yet if P would be the RB." So yeah, FMIL took it upon herself to tell FBIL and FSIL that we wanted P to be the RB. I'm soo peeved right now. FI doesn't want me to say anything to FMIL, he knows it will upset her if I call her out. Apparently I can't share any details with her until I finalize them myself. Oye, I'm just frustrated because now I feel obligated to have P has the RB and that we couldn't ask them ourselves. Ok vent over.
