well, that's something. All the same, I wonder what his reason was for not wanting to be with you. Was he missing something on the telly? Does he get nervous when away from home? Does he really need to be in the Four Seasons before he can abide your company? And why the sarky texts?
Perhaps you didn't have that "for richer, for poorer" thing in your wedding service.
Anyway, it's your birthday, have tea, enjoy the theatre, and don't spoil the time by wondering why he's behaving like a jerk. Sort it out when you get back, not before.
