I'm not sure how you can just "not care" about that. This is EXTREMELY disrespectful behavior, and you're just going to sit there and let him continue to disrespect you and say you don't care? Please have a little more respect for yourself and quit putting up with this never-ending crap from your H. Next time he pings you tell him you've given him dates and times the last two times he asked and he didn't dignify it with a response, so he needs to find his own vet.
