Why does this guy care what I do?

I don't know him he just lives in my town. He catfished me under a weird username. Called me a drug addict, whose slept with 20 people, and said how I ugly I was. In a nutshell at least, not the exact words but Jesus I was just in sweats and completing my summer classes, I was burnt out from working two jobs and going to school. Is he just a BULLY?

Also I have my degree, has worked in corporate, and used to be a stoner but not like drug addicted? This guy really seems to hate me and I can't figure out WHY?
