Urgent opinion required!!

Hello everyone, I am currently facing a situation and need advice. I am 22 and had a friend in university who is not financially well and I don’t have any problem with it nor I ever said anything about it to him. But whenever we meet (mostly during exams) he abuses my parents, father’s profession etc. I usually never react to these abuses and try to ignore. But recently, after exam we went to eat something after exam and he started taking nooks out of everything the place I took him to, the food ( for which he was not paying btw) I had enough of it and stopped talks immediately as a normal person but now he is saying things like these things are common and friends say these things. I want to ask is this normal, or have I made a mistake?
