He just sent me this text:
I hate [stuff he hates] even more than you hate sex!
He thinks he is being funny - in the haha sense. I think he's being a whiney, passive agressive arse about it, and that this text alone is a damn good reason to give him plenty of actual reasons to whine.
We usually have sex at least twice a week, by the way, so it's not as though he never gets any.
