I really miss my ex, but he made me cry.help.?

I'm 15 and i dated this 18 year old for almost a year. Besides all the fighting and disagreements, he really was a good guy. I haven't seen him in about three months, but we've been texting as friends. Well, tonight i need someone to talk to and i texted him and his "girlfriend" went off about how im a ***** and he loves her, blah blah blah. And then he was like don't talk to me anymore. But i know he'll text me tonight when he's not with her. But, i miss him but tonight REALLY pissed me off...should i forget him? or keep trying? and i'm not trying to sound rude, but i'm for sure he still likes me.
