Hi, I was looking for some advise/sign posting to support my son. He is autistic and is 21. He has become obsessed with a girl he likes, but it is really affecting his mental health. He can be overwhelming for her. But if he doesn't hear from her, he says he will go off and that is a worry. He went off on Monday this week, and we weren't sure he was going to come back. I would like to try my best to support his and try to get help for the unhealthy friendship. I know he struggles with social situations.
