Should I Trust My Gut?

When I got off the school bus this boy that I used to like a lot asked me do I miss talking to him. I said no because he turned out to be a jerk because he treated me like shit when we were friends. We messed around a couple times but he would never try to talk to me or be nice. I text him to leave me alone and now he suddenly cares after us not talking since last year. I feel like he just wants to mess with my mind again. Should I trust my intuition ?
