Ex boyfriends

So basically, me and my ex broke up around 2-3 months ago. It was hard for me and easy for him to move on. Now, I’ve dealt with it and told myself that I should stop acting so depressed all the time and I have. I feel so much better at school and home as I try not to think about him as much. Obviously he does come into my mind at times but I can get rid of it by distracting myself. The only problem is that he keeps trying to make me jealous by saying another girl’s name out loud every time. I ignore it and act normal. And to be honest, I don’t really care but he is really annoying me. I think I’m getting over him, but I still kind of like him - but not much. Tell me what to do!
