Am I being unreasonable?

I don't see how I am. But I would appreicate opinions from others.

Basically, someone on the spectrum is obsessed with me and keeps sending me messages on Facebook. I asked him to stop contacting me all the time. He claimed that's what friends do. He's moaned a few times because he doesn't see me that often.

We met at an Autism group and a few times, I've said for various reasons, I'm not going, which seems to have really upset him. He also wasn't happy that I said I wasn't going somewhere with him due to noise. He can't understand that's a form of torture.

He said last night that he wants to get the branch officer of the Autism group, him, me and his two support people together to sort this out.

There's nothing to sort out. He just needs to understand that I don't want to be contacted all the time.
