"Weddings are tricky things! I've done it loads of times, and never get over the nerves..." admittedly, he'd always had that nasty tendency of doing it by accident. Some alien cultures had such weird ways of proposing, and some of them got a bit nasty when you tried to get away.
At least this time he wasn't the one getting married. He'd always loved a good wedding, especially when his companions were involved. "At least I'm not missing this one. Don't think Amy ever forgave me for being late."
Yes, he'd technically not existed, but the wrath of the Pond didn't take things like that into account.
