<human>: We have been absolute best friends since sixth grade (11th now), and I always felt like there was something between us. Apparently so did he, but the catch was that he had a girlfriend.

This summer we became especially close, and we were spending almost everyday together as best friends. Then randomly one night out of no where we were about to make a huge mistake (he was about to cheat on his girlfriend, to say the least), and I told him to stop.

It was crazy to me because I had liked him forever. Next thing I know he calls me the next night at midnight and told me to come outside because he had just broken up with his gf of 6 months. I was freaking out.

So yes, the next week consisted of sneaking him into my room at 2am to do things I now regret, and swimming at the lake. He wasn't keeping me a secret either, he was probably telling more people than me. I thought it was going well.

Skip to the crappy part: maybe a week into this, I was taking my sister out for ice cream. I drove by his house and his girlfriends car was in his driveway. I seriously was just stunned, I didn't know what else to do. I just waited until the next day to say something, and his response was "I'm sorry". I guess they worked things out?

I haven't spoken to him since, he never tried. I think about him every second and I feel like I don't cross his mind! I just want to be friends with him again...

extraneous side stuff if you guys care enough: he did this in the middle of my parents getting a divorce and us moving out of our house to an apartment. Pretty rough, but I think I handled it gracefully!

I had to use a throw away because too many people know my real account! (sorry)

Can you give me a shortened version of the text?
<bot>: moved too fast and then he left without saying a word, and now I lost my real best friend. My fault? Should I say something to him?
