Mia it sounds like he is turning into a nut job, but you should not let that change your perception either way. Don't feel sorry for him, as job said you cannot get through to him now. Maybe remind him of the ways that he is able to contact you if needed, just a gentle reminder? Not sure why you would need to actually tell a grown up man about the difference between leaving random messages and emergencies but hey ho, that's what we need to put up with.
