Me and my ex Cris have broken up like 5 months ago since he cheated on me with a ugly bitch who could never compare but like me chill

Anyways the problem is that I still she him around for example at school at the mall like just around town and stuff, it's super duper awkward he's always looking at you and your friends started to noticed

"Who is that guy why is he always looking at you do yk him?" She ask confused

"Uh nah idk who he is girl" I say while giggling

Cris heared this and it make him annoyed and mad

Next day at school

You were walking through the hallways to your next class when all of the sudden you stopped when someone tapped your shoulder, it was Cris

"Why are you acting like that" he said annoyed

"What?" you asked confusedly

"Why are you acting like we never happened?"
