When I had sent out my invites, a bridesmaid of mine was engaged. Since then they have called it off. But her ex and her are so on and off again that I don't know if I should expect him to come. I know she is allowed a plus 1. But I fear that when the wedding comes around they will not be together and I had invited his children. So that would be 3 meals that I would be paying for that wouldn't be used. The other issue is that since he broke off their engagement twice this year, I don't particularly like him and really would not want to see him on my day. (She knows I feel like she should just move on). What should I do about him coming?
