Ex boyfriend wants to talk


I'm currently in high school. I broke up with my boyfriend months ago because he was talking to another girl. He hurt me pretty bad. He's texted me multiple times saying that he wants to talk or at least be friends. We now have a class together and he stared at me the whole class period. After school he then texted me saying "Hey, are we at a point where we can talk? Class today was pretty rough on me." I don't know if he wants to get back together or just talk and be friends. I definitely don't want to be in a relationship with him, and I'm even hesitant on being his friend. Should I talk to him? Or should I let him be so he can move on?
