Why act this way?

I left him. He showed/made a video to someone of me giving him head without my knowledge. I change my number haven’t talked to him since! Well yesterday day I was with some other coworkers outside before work! He walked up and I should of left the moment! One of the coworkers I was with asked him if he had a good day off and he said yeah I did some extra Curricular activities and my coworker said “oh you went to the gym?” he said “no but yeah some extra extra activities!” They looked at him foul and said nothing!
is this guy trying to make me jealous?
Is he try to prove to me that he moved on?

I left him! Why can’t he be civil that things didn’t workout instead of wiping it in my face when he get laid. If I did that he’d be broken!

Why act this way?
