I'm going to cut an autistic friend out of my life
Why do you feel the need to cut a friend out of your life?
I cannot handle him anymore.
I understand that it can be tough to deal with those who have autism. But just abandoning a friend because of it seems a bit much.
I'm very scared and I don't want to deal with him.
Maybe you can do some research or talk to a professional in order to learn how to deal with it better. Abandoning him will hurt his feelings, you should try and understand that.
