What is this guy to me?

This is really complicated. So I’m trying my best to explain. And sorry it’s so long. Well I’m trying to get over this guy right now- this guy that I fell in love with. There’s this other guy, we were really close. He was one of my best guy friends. Last year we liked each other but I was in a relationship and he was like a player… so nothing happened. But I still kinda liked him. Few months ago this year, he told me that he still had feelings for me. I didn’t know if I wanted to believe him because he’s lied to me before like this and when he told me, he was have a ‘break’ with his girlfriend. So he was still pretty much in a relationship. When he told me that, it was pretty much the same time I decided to get over him. I didn’t know what to do but to pretend like it didn’t happen. I don’t know if I like this guy. He makes me feel warm inside. It’s like I’m walking down the hallway at school with a friend of mine and I see him, we hug and it’s like I forget about my friend and it’s just him and I. It’s actually happened before. I totally forgot that my friend left and I was just standing there hugging him. He’s kinda a popular guy… in a way. Total flirt. When I hug him… we hug… let go and talk for a bit then hug again… then release and hug again… It’s weird… because I never realized until after it happens. It’s like I stop thinking. Do I like this guy? Or infatuated with him? Rebound guy? I’m so confused.
