Help with ex bf?

okay so in may, he broke up with me because he "didnt have time for a girl" and he was going to college in a few months. we didnt talk for three or four weeks. he then iMs me and we start fighting.. we put everything behind us and decide to be friends. well a week ago he was iMing me every day and wanting to talk at night-i felt like he still liked me. well, two days ago he was being reallllly rude and i finally told him i didnt want to talk to him anymore and he hasnt said anything because he went out with this girl today. i feel like he still likes me but now he wont even talk to me-i know i told him not too but i would of thought he would have tried. do you think he still likes me and trying to make me jealous? he always denies he doesnt like me so idk!
