I met this guy at a party during my freshman year. He was cute, sociable, and flirty with me but also drunk at that time. I developed a crush on him because he was the first one to take interest in me. We became facebook friends, but because of our different schedules, group of friends and lifestyle, we never got to truly hang out despite me being good friends with his best friend/housemate. In terms of personality, we are complete opposites. I'm pretty quiet, studious, and shy while he's outgoing, and very much playerish. The only times I actually got to see him were at parties every once in awhile, where we just say hi and hug. I never had a real conversation with him since after the first party.
During my second year, I tried really hard to get over him. Not seeing him for a lot time helped with that process. I hooked up with other guys but they were all casual relationships. School just started again, and I'm seeing him around more often at parties and so my crush on him is back. At the last party, we did up dancing with each other. There is some obvious physical attraction between us:smiling, stealing glances but we can never talk to each other normally. Our conversation the other day went like: "Hey,*hug* how have you been?!" and "Same old, same old." and ended like that. For other guys, I can talk and even flirt with them but with him, my mind just draws a blank. I realized that everytime I see him, my eyes focus only on him and I never remember or realize who is standing next to him. I am constantly thinking about him.
What should I do? Am I imagining that there is something between us and try to talk to him, or should I just stop and try to get over him again?
