This shouldn't be bothering me, but it is.
One of my bridesmaids has a boyfriend - they've been dating for 4 months or so. I've only met him once, but he is is invited to the wedding as her guest, AND the rehearsal dinner. However, my bridesmaid (who is very easygoing) told me that he is "not going to come to the wedding ceremony because he won't know anyone there." To me, that feels really, really rude and I'm not sure what to do. He doesn't really know us, but we don't know him either, and are providing two meals for him and having him at the wedding. It's such a little thing and the wedding is only 4 days away, but it feels like he's just coming for the food and the party, and nothing else, and his unwillingness to come to the ceremony is affecting the car situation, as now the bridesmaid will have to leave her car at the church and can't do so overnight. By the way, she is totally fine with this. What would you do?
There is nothing you can do. While its rude, its his choice.
And he is not required to help in the car situation. If it doesnt bother BM then dont let it bother you. She will figure out what to do with her car.
Honestly, if my wedding were in 4 days, I would give -2 shits about this.
