Why don't some guys understand me?

Sometimes it is hard for me because I was diagnosed with high functioning autism and it is hard to communicate with guys at times and to keep a conversation going therefore they don't understand what I am saying sometimes because of my communication difficulties. Therefore I am left ghosted. They get annoyed at my autism symptoms when I try to communicate with them. Why are some guys not the nicest to autistic woman when it comes to trying to have a casual relationship?
