Aww but wedding dress and wedding reception and the big dance moment and feeding one another nummy cake! Are you certain you want to elope? You should have your gay wedding and do it gaily, and whoever is being terrible doesn't have to take part. They can stay home and miss out seeing you being happy and in love. You shouldn't deprive yourself of that, because of someone else!
Unless you really want to elope, and then that's fine too. I have had plenty of friends do that, and they've been perfectly happy and never regretted the weddingy things.
You definitely need a happy bunny gif, because be happy! You're gay marrying an archeologist and that sounds exciting, if not a little nerdy dirty. <3
