Could this guy like me?

I catch this guy staring at me a lot. Our eyes would meet and we both turn our direction to some where else. We did talk middle of the year but he stopped talking me. I have no clue why? We are from different social groups. I'm consider as a nerd and he is way more popular then me. But he sat next to me in english class and we would talk. I would mention my bf a lot and he seem he wasn't bother about it. Last convo I had with him was when he was making a v-day for a reason I do not know and he asked me if I would like if someone made a video like his for me. I said sure and after that he wouldn't talk to me. Months past and just the other day I caught him staring. What is going with this guy? Why is staring at me? Could he like me or am I being paranoid?
