Trust?!

So kids at my school and making fun of autistic people. I told them to stop bc my friends brother is autistic and I didn’t want them to make her mad. My ex told me to quit being salty and to quit trying to control him, and my best boy friend tried to stick up for me and he just got made fun of, too. There was this other kid that told me that he would try to stop and tell my ex to stop to. So I had a convo with him about it and Thai is what happened.

And lily is his wannabe girlfriend

Please no hate and help me on what to do
