<human>: Can you provide a brief rundown of the text in within 3 sentences?

So, I was seeing someone, short-term, a few week but sleeping together & dating... we were still not 100% what 'our thing' was..

...and a really, really good friend of mine, with whom I have a lot of chemistry seemed to want a relationship with me. So I broke of this 'ambiguous thing' to explore this option.

Nothing happened.

But, as I broke things off with the first guy, I realised that I actually didn't want to end things, and that I enjoyed them... but, too late! He wanted to know the situation as well, so :/

But, as nothing happened with the other friend guy... would I be the world's biggest jerk for contacting the first guy again to see if he would want to meet up? It was a mistake ending things. I know. I messed up, and I do really like him, but I was very conflicted that week.

If you were the first guy, how would you feel? Ever been in a similar situation? What should I do when I really miss him?
<bot>: broke things off with a guy I was seeing for a few weeks for someone else. Nothing ended up happening with other guy, and I really regret ending things with the first one. Can I contact him again?
