How does my boyfriend have the time to cheat on me?

I don't understand. He is autistic and I know he is cheating on me because I saw him texting other woman. How would a woman even want an autistic man. I am autistic as well and sometimes I don't have luck on hook ups because guys think I am weird and they think something is wrong with me and all I am is ghosted. Help me please. How does anyone even want him? I broke up with him when this happened. We were together when this happened. I am disturbed by this.
