I made a friend mad at me. Should I say sorry? Should I continue sending him messages? Or should I just ignore the fact that he has been ignoring me.

I have a friend in online school. We’re pretty close because we have at leasti 2-3 same classes each semester. However, I think my friendship with him is purely professional/ academic. We share notes, reviewers, rants about our classmates and professors. 

But I don’t share much about my personal life and family because I sometimes find him creepy and too nosy about my life.

Makes comment about our house since he can sometimes see it on the background, asks about my family background, what I do etc.

He also comments a lot about how I look in class like “you’re prettier when you wear make up”, “please stay safe pretty”, “you look hot wearing that blazer” etc. I told him it’s making me uncomfortable.

Lately, he found my instagram and followed me. I blocked him. He got mad at me.

I know I am only setting boundaries but knowing that someone is angry at me keeps me up all night.
