Mari,
You need to be away from this guy. He is obviously trying to make his problems your problems and isn't ready to be back at work.
First of all he knows no people boundaries, touching your stuff the way he did.
Second, he needs people skills.
Third, just because he's gay is no excuse for being a jerk.
Fourth, don't be mad at him for not going to YOUR doc. He's a supposedly grown man and makes his own decisions. If he's messed up, he did it. Personally I believe the man needs another ECT dose!
And finally five, MOVE! Get that AC fixed and do what you have to and take care of you!
I would have taken this guy's head off by lunch. So you did really good today! BRAVO!
