Love, a game of what though

Ever played a game where your teammates sort of tell you the rules but then make you guess at the others. Well that's how I'm playing this game and it's not even a game! It's love! Yes love can be a game but I don't want it to. It would be nice if it was in black and white but right now it's in bright yellow and peach. I can't tell what the rule book says and I'm starting to get a little irritated with my thoughts but I can't just STOP THINKING! (Trust me if I could I would BUT I can't)
I'm dating a boy I've known since the 2nd grade and we've dated on and off so I don't know why I thought this time would be any different. I mean nothing against him because he's a great guy but I have or thin I have feelings for this other guy I just met and haven't really talked to much. Yes I know your questioning how I know I like a guy if I haven't even had like a real conversation with him, but you don't need words to tell what someone else is thinking unless their body language is not saying all that needs to be said. The way we talk without words isn't magical by any means like heart skips a beat magical but its... I don't know exactly how to explain it. We make each other laugh and it feels like if we were together it would be one of those normal relationship.
My friend told me I should just get to know him first because I may like him now but once I get to know him I may not like his personality. That or we may not click, but either way I would lose two people instead of just lose one gain one sort of thing.
I'm usually not that shy. If I want something I go after it and except the outcome no matter if it's the way I wanted it or the way I didn't want it. Either way it's the way it is supposed to be. For some reason though I can't just go up to him and start a conversation with him. I don't know if it's because he's a year older than me and I haven't had a chance to really get to know him or if it's just him. I'm working on figuring that out.
I like him because he is nice and funny and pretty darn cute. He's muscular. White but muscular. And when he messes up he looks at me like I'll give him the answer or by looking into my eyes he can find it. (He's on drumline with me. I forgot to tell you but this wouldn't make since if I didn't tell you this tidbit of info.) It's sweet. I usually don't like making eye contact with someone, but when our eyes meet I want them to meet again and again. Plus he makes an effort to make eye contact with me or just looking at me. He usually looks around the room and then his eyes stop when he finds me even if only for a second, his eyes still stop.
I think I love him. But the bad part about this situation is... I HAVE A BOYFRIEND! I feel guilty thinking these thoughts! Maybe i should just go to jail. Although there's nothing to do in jail besides...
THINKING!
