I've recently ended a bad relationship I was in with someone who has Asperger's syndrome. Their behavior was too much for me to handle. They do not seem to realize that the relationship has ended and they keep wanting to discuss every single thing that went wrong throughout our entire history together (i've known them for years). They insist that everything is my fault and I am to blame for all the hurt they have caused me because, according to them, I was the one who hurt them first. Its a never ending cycle. What should I do?
