There are so many married men who post into these forums because their wives won't give them head AT ALL, and this guy is ticked because you just had major surgery a week ago? Plus you are dealing with THREE kids at demanding ages?

Are you looking for objective confirmation that he's being a jerk?

Well, yes, he is.

You might want to ask if he's having trouble at work, or if there's something else going on, but for him to say, "fine, I will just take care of business my own way" is a bit beyond the pale.
