<human>: Could you distill the essence of the text into 1-3 sentences?

I met him over a year ago. We had immediate chemistry and quickly became friends. He is highly attractive and I've had a crush on him basically since we met. Unfortunately, he's been in a relationship with a girl at another college for over three years... 

I had a brief relationship earlier this year that served as a distraction, but since I've been single again my crush on my friend has escalated to full-blown love. It's kind of amazing that we've managed to become close friends despite my general awkwardness.

We talk several times a day, sometimes about deeply personal things, and spend large amounts of time together. Sometimes I'm certain that he likes me back. He laughs at all the things I say, looks at my eyes all the time, tells me that he's glad we're friends. We're both kind of weird but we "get" each other.

He doesn't mention his girlfriend often around me. I haven't hooked up with him and I try not to flirt with him out of respect for his relationship, even though it's really hard not to act on what we have. I'm usually pretty good at regulating my emotions and I don't fall in love often, and I haven't had a crush like this in a long time. 

My conscience tells me to wait until he breaks up with his gf, obviously, but I'm afraid I'm just going to confess to him and ruin our friendship, or try to get with him when we're drunk and ruin it that way. 

No matter how much I like him, our friendship is really important to me and I don't want to risk it. I'm just not sure how much longer I can keep this a secret. Should I tell him? Try to spend less time with him to protect myself? Or just keep doing what I'm doing and hope for the best?
<bot>: Huge crush on a close friend, he has a long distance gf but I get the sense he likes me back, not sure what to do.
