Last Sat was my bridal shower which my MOH hosted. We had a mimosa bar, and one of my bridesmaids (J) drank way too much. The shower was at 11am & she didn't leave until almost 4pm because she kept drinking. Then she kept saying we should open another bottle of champagne, but my MOH would not (thank God!). J was also making jokes about how she could just sleep in their yard or on their porch swing if she drank too much. No one else there acted like this (or even close). The shower was at my MOH's house, so it was a huge imposition on her that J overstayed her welcome. I wasn't able to leave either because I didn't feel like I could just leave when a guest was still there.
Both my MOH & I are very concerned this will happen again. We have the bachelorette party coming up which will be a pool party at someone else's house. No one will be drinking so much that they need to sleep there, including me (I have epilepsy, so I am not a huge drinker.). Then there will also be an open bar at the wedding which we are only serving beer and wine. I talked to the venue owners a while ago about what if someone drinks too much; it's an all-inclusive venue. They provide the bartender. They said the bartender will cut people off if they seem like they are drinking too much (going up to the bar too often, etc), and if necessary they will call an Uber.
My MOH has said that if there is a problem at either of these events, she will say something to J. If something happens, it needs to be taken care of, and I will say something if necessary. But I obviously don't want there to be any drama or a scene. This is not the first time something like this has happened. It happened a lot in college. One time, she tried to kiss my boyfriend at the time. (We were 18-22 then. We are 43 now.) And of course she didn't take it well, and there was drama.
I'm trying not to stress over it, but I don't know what to do!
