I guess I'm just wondering if you've ever told him what he did or said to make you think he's a jerk. I ask this because it has happened to me many times that people have shunned me over something I said, but never told me what it was. Sometimes they did tell me months later, sometimes not at all. This has happened both at work and in my personal life. I think it's because I'm probably on the autism spectrum. People expect me to infer and understand things without being explicitly told. I find that happens often with women. In general, men need more direct communication.

I also think maybe putting it in writing would help. That way it will give you time to think and not have to worry about his reaction.
