You've got a point about the FB page.<quoted text>
Unless she saw his picture on her friend's facebook page.
I think the bride should be given a break. You ask your friend to be your moh, soon before the wedding she starts dating some guy and they're always bickering. You want that drama at your wedding?
I'm not giving the bride a break because I agree with Matilda - uninviting the already invited is the bigger Drama Queen move. And we don't know that they are "always bickering." My guess is that they were bickering because LW went to a 3-day bachelorette party.
