**Sorry if this has been asked, haven't seen it before**FMIL visited this weekend, and declared that she will be paying for our rehearsal dinner (we are paying for the wedding ourselves). We weren't planning to have one and told her as much. With a small wedding, we didn't think it was necessary, and we wanted to put our limited budget to making the wedding as amazing as we could, rather than splitting the $$ among two events. Anyway, FMIL was surprisingly emotional about the rehearsal dinner and said that not having one would be rude. Ultimately, I guess we won't fight her about it. But is it really rude not to have one? Also, what are our planning responsibilities if we do it? Is it like a shower where she hosts and we just show up? Or do we have to plan it as well? Thank you!
