So my friend and I are both getting married both in "destinations" (different locations, different months). I RSVP'd to her wedding super early, booked tickets, made sure I got time off work, etc. She just RSVP'd on the very last day and told me she couldn't go to my wedding because she's booked her civil ceremony the same weekend. She insists it's because it's the only time her family could go and she really didn't find out until the last day I gave to RSVP. I also have a minimum headcount at my venue and I'm also a little short on people so I was really counting on her going and without her I'm a little bit screwed. I'm irked but I don't want to cause drama or make a big deal out of it. I can't get out of not going to her wedding, but I really don't want to go to her bachelorette party, where I'm expected to bring gifts and pay for her food, decor, etc. I already said I'd go, but now I'm thinking of backing out. Is it bad form?
