<human>: Can you condense the text into a few key points?

We had a wonderful sexy time together with not a single fight. No rose tinted glasses here, we really never argued. 
Out of the blue (we were making plans for the future) he left me for someone he met on holiday.
I've not been able to move on at all despite doing NC and keeping busy, I still cannot think of being with anyone else. 

So I saw him, there was flirting and it wasn't at all awkward. He was very complimentary. He told me life is crap at the moment. He fights a lot with this woman and that it was great that it was nothing like that with me. He said he made a bad choice that he now has to live with.

I saw him again yesterday and again it was all happy and from my point of view there was so much sexual tension. He looks at me again in that way. You know the one. That look.

I don't know what to do now. He doesn't have to live with that choice. I'd have him back right now. No question.
Could he be waiting for me to let him know that? To me it's obvious, I've been living with missing him all this time, I also miss the greatest friend I've ever had. I assume he knows this but do I need to spell it out?
But then there's that playing hard to get thing I hear men like!
<bot>: Ex said he made a bad choice in ending it. Do I make a move and let him know I'm still interested?
