Guys, why does he keep staring at me after we don't talk anymore?

So there's this guy, and we're not ex's, but we were really close friends and I thought he liked me because of the things he would say to me, and until he stopped talking to me (presumably because he thought I wasn't interested in him in that way) I realised he is the first boy I've ever been in love with.
We haven't spoken since November, and I told him how much I missed him, and got my friends to talk to him for me, and I even sent him a message a few weeks ago saying "This is awkward and cheesy af but I love you"
Recently, we've been made to sit closer next to each other, and I keep on noticing him staring at me. When I make eye contact, he will stare back for a few seconds, then look away. Sometimes he looks unhappy, other times he look intrested.
He isn't staring at me because I'm loking at him, because I hardly ever look at him. But I've been in love with him for months without even talking to him. He has a new girlfriend, so why is he staring at me? Does he just feel awkward being around me because of how close we were

Thank you x
