My wedding is a little over 3 months away. I am getting ready to send out invitations and since we have a smaller budget than is usual for a wedding, we're only allowing plus ones for those who are married or have been in a serious relationship for at least a year. The main reason for this is because if they've been together a year, chances are me or my fiancé or both of us have met them more than once and know them enough for them to be at the wedding. My matron of honor lives out of town and I'm getting a room for her and I to share since she's not with anybody right now. This has been the plan since I started planning it. She also agreed to pick up my dad who lives in the same town as her. She and I spoke this morning and I advised her of the plus one situation and reminded her about picking up my dad, a conversation we've had more than once. She tells me she doesn't remember agreeing to pick up my dad and also tells me she was planning on bringing a guy and having a sex filled weekend. Normally I wouldn't care who she's messing with, but this is my wedding. First, the room is only for her and I, so where's he going to stay? Second, my fiancé and I don't want someone neither of us even know, let alone met, at our wedding. (And before you ask, yes, I've discussed this with him). I'm just wondering what to do at this point. I feel like this is time she should be spending with me, at least the day before and morning of. Am I wrong? What should I do or say?
