So stop wondering about it and ask the man what the heck is going on with him.
I'll be honest, my first impression when he was putting you down and making comments about having to get drunk to ML to you and him not having any privacy....really scared me for you. My thought was "there's more going on here." I hate to put this out there....but is it possible there's someone on the side? Or at least some type of activity you don't know about that he needs privacy for?
As for his behavior as of late....yep confusing, I can understand that.....you need to ask him what is going on. He's sending you such mixed signals. Stop wondering, ask...and if you aren't satisfied with his response, start looking to see if there are any clues as to what might be going on.
Are there stressors at his work to explain his behavior? Does he appear to be hiding anything? i.e. clearing the history on the computer? Just stuff to pay attention to. He may not be up to anything, just stuff to be aware of.
