So, after talking to Kevin last night I realized something.
He's just a friend.
All this time, I thought I had a crush on him. Only because I wanted to get closer to him, and he always pushed me away. I misinterpreted that as a crush, when really, now that I think about it with a clear head, I just wanted a better, stronger friendship. And now it looks like there is a possibility.
He has a girlfriend, and she's really nice. Kevin has made her very happy. And I'm very happy for them both.
