I have experience with this mojave. I often become morose and over-analytical when I think someone may be 'mad' at me. I agree with whatbeanbelieved, if he is 'mad' it is his problem and not yours. You've opened the lines of communication and now it is up to him to communicate or not. I also don't mean to sound offensive. I just know that when I feel someone is mad at me, I make it much of my own problem, when it is none of my problem at all. If I've done something to offend someone, that is a different story, but the ball is in his court. Perhaps try to work on acceptance? This is not always easy, but it can bring peace of mind.

Best wishes to you.
