that one bi guy

Ive thought about that guy being gone for a little while, and then I started thinking about this guy I used to talk to in the beginning of the school year.
I still remember when we walked into each other. I was nervous and he seemed like such a cool person, so I started thinking 'why the hell would this person want to talk to me?' So I started pulling out all the coolest one liner's I knew. I suck at small talk but I tried to keep up with the conversation.
One time we even held hands, and I realised he was afraid of people thinking he was gay when we came across some of his friends.
A couple times we almost kissed, but I knew it would be a good idea to tease him at the time, so I would grab the of his neck with one hand and his leg with the other and I would stop once I felt my lips brush his. Then I would smile and push him away once I realised we where still in class.
I moved out of that class and we kind of stopped talking. Now every time I see him its with his girlfriend.
When we would talk he didnt know if I was just a straight guy messing around or just some gay guy, so I asked one of his friends to tell him that im gay. Then the next day when he was with his girlfriend he came to say hi to me. At that moment I knew he still had some feelings for me and im trying to talk to him more but I only ever see him for at least 10 seconds a day.
