<human>: Can you give me the gist of the text in a nutshell?

Alright, this is a pretty long story, but I'll try to keep it short and sweet.

Over the summer, I had recently broke up with a boyfriend of 2 years, and this guy - we'll call him JD - had soon after messaged me on facebook, telling me how he would really like to get coffee with me and get to know me (he was one of my good friend's friends). I agreed and we met up and it was the best day. I ended up staying the night at his place to cuddle that night, then we hung out with each other for three/four days/nights straight and had the best conversations. I fell head over heels for him.
(here's where it gets complicated) I'm an idiot, and didn't think I was good enough for him, so I started messing around with someone else and he kind of went off too so it wasn't awful on either part. I then started actually dating this other guy - for about a month - and I broke up with him because I realized I still had feelings for JD. 
well. now JD has a girlfriend.
BUT we're starting to become friends again, and Monday night JD was supposed to come over and have dinner with me and a few friends. but he bailed and said "I like you a lot and don't know what to do/how to feel" in a text as the reason he didn't come.
I really like this guy. and I don't believe in missed opportunities so I've texted him a few times explaining how I kind of feel. But he won't discuss it with me. And I don't want to be a homewrecker. I'm just very conflicted.
<bot>: I really like JD, we have a past - he has a girlfriend now, but has led me to believe that he still has feelings for me. What do?
