I need guy advice.

So this happened a few months ago. I'm 16 and the most popular jock in my grade at high school started talking to me. In two weeks, he asked me out. Now before this, I had a really low self esteem, which he boosted and he made me feel good about myself.

After he asked me out, we were informally labelled by the grade as a couple. We talked until after Christmas, when without breaking up, he cut off all contact. He didn't say anything. Just stopped talking to me. He wasn't seen with another girl, and his parents knew about me.

A week ago, he moved to Canada. That's what everyone said and also what geotag his snapchat story had. But today his geotag was the place where I live. I don't know if he's moved back, or what, but if he comes back I'm going to have a lot of bad memories resurface. I'm really confused and I don't know what to do.

And yes, after he stopped talking to me, I found out he was a total fuckboy. But I think I still have feelings for him.
