Wow...now he has issues...I'm really sorry for your experience, that must have been horrendous for you. If you want to feel less angry, though, accept that this man is very, very mixed up indeed. He sounds extremely damaged and obviously something awful has happened to him.

I never know whether stuff like that helps others or not. It helps me if I feel angry at the way I have been treated and offended at words like "weirdo". If, like me, you struggle to feel confident in yourself those words can get to you and make you feel bad. Remember that those words have come from his issues. In your heart, see that you have met someone with severe problems, internally wish him well, hope that he is able to sort himself out and become a more balanced person, and move your mind on to other things.

Sorry if this in any way makes you feel worse. Some people feel better if the other person is just a prick (my friends are like that), but I feel better if I can see that everyone is struggling and if I can see them as a human being with terrible problems. That helps me to let go of the event and not allow it to linger in my mind. It provides closure to me over unpleasant events.

I don't know why I'm different that way, but I just thought I'd offer you what I would need in case we were similar.
