What the heck just happened here?

I added this man who I’ll call *Dave;* from an Autistic friendship and dating site. One minute, he was acting like a friend, the next he was lovebombing me and then he posted all these disturbing things on Facebook, about being broken and breaking up and a cartoon of a woman (who I think was meant to be me); making mean remarks, saying something like; ‘Why do I feel so disgusting? Do you love me? Do you love me? I want to puke!’ After making sure Dave wasn’t suicidal, I blocked him. Both of us have Asperger’s and I’m bewildered by his behaviour. What on earth was going on there?
