Search Results: leaving a guy for an ex

He's my age, 17, and he comes up to me to chat and spend like, 2 hours talking (like 4 times/week). We go to the same college and we are both musicians. In fact, recently he saw me and came to sit with me. Then 2 of his friends came and then mine came as well so we were more like focusing on out friends rather than talking to eat other but we still said some things. According to my friends , it is like we sort of avoid each other but or close just unreachable... I myself know that I am really good at hiding my feelings. I did like it though that he came to me. I did notice though that when he talks to me he holds eye contact and gives a half smile sort of. He laughs at what I say but it is like he is really good at hiding it. My friend also noticed him a few months back always looking at me. Now it's like he knows I'm there and looks at everyone but me... I do that as well. I do go to chat with him as well so it is from both sides. He also comments on my posts whenever I say that I achieved good grades, and I do so myself on his posts. He also remembered me telling him my favorite composer, that was sweet haha. We are always encountering at the library, it is like (at least from my end) that we go there not just to work but to meet or see each other. I am pretty good, but I still show that I care. When he sees me he smiles automatically and when he comes to talk I see him trying to reduce the smile.
My friend noticed is that when I was leaving the library, his friend kept looking backward at me and my crush tilted his body slightly but not completely towards him like he was before when I was sitting in front of him.
lastly, the day before he initiated chat twice, once to talk about a guy (our convos also start with an excuse, for ex, him saying: "do we have rehearsals tomorrow?" Then the second time he sent me a draft of a music composition he was working on. What do you think? My opinion is that there may be a hint of interest but it's not clear.
