<human>: Can you provide a brief overview of the text?

I was recently out with a bunch of friends. Among them was a friend and his ex. They had recently split up, but were still friends and hung out. She was quite clearly into me, which is saying a lot since I am utterly useless at picking up hints.

So when we end up a bit out of sight from the rest of the group, I lean in and kiss her. And she kisses me back! We start making out and hands go places where they probably shouldn't in such a public setting. But then she suddenly stops and says "No, I can't. I'm with Eric.". Turns out they weren't really broken up. At this point I'm just in turmoil and I end up avoiding both of them for the rest of the night.

On one hand I feel like shit for making out with a friends gf. Even if they would have been broken up, ex:es are a touchy subject and generally off limits. I've always taken pride in having a strong moral compass. But when things get tricky, I apparently fail miserably.

On the other hand, the whole thing has shaken me to my very core. It was over a decade since I last made out with anyone. I had almost completely resigned myself to the idea that no woman would ever find me remotely attractive. And here is this gorgeous woman, eight years younger, that looks at me with such lust. The significance of that is more than I can put into words.

So here I am, trying to juggle this storm of emotions. Haven't talked or seen any of them since then, so I have no idea what's going on or if he even knows. I don't know what to do. I think he deserves to know, but can anything good come of it? Or is that just an excuse because I'm too much of a coward to own up to my role in this?
<bot>: Thought they were broken up. Turns out they weren't. Horribly conflicted about what I feel, and what to do next.
