Do you think he's being a jerk? Am i being a retard for actually still caring about him? HELP ME?

He was my first boyfriend and we broke up a week after he asked me out because of my parents -_- but the point is that i cant get the thought that we were pefect for eachother out of my head. He's an amazing person but he has a lot of emotion issues but im the kinda girl who loves helping people and giving them advice an letting them know that their not alone so thats what i used to do o him and i still do sometimes even tthough we're not together. He texts me sometimes and when he does it always ends up being a therapy session for him lmao but recently he's been really mean to me. His friends girlfriend even pointed it out and said "why are you being so mean to her?!" and he tries to embarass me infront of his friend and asks me things like "why are you talking? why are sitting next to me?" and he mimics my voice. so i just want to know how to get over him or if i even should? do you think he still likes me but is trying to hide it? i know i dont deserve to be treated like this his brother even says how im an amazing person and hints at things to make me sit by his brother and stuff. so any advice?
