<human>: So we got on pretty well at this work thing and ended up going for a couple of drinks afterwards, just us. We had some interesting conversations and had a nice time, and I ended up walking half way home with him because our conversation was so good!

(btw we don't work in the same place so I probably wont see him at a work thing ever again)

He asked for my number but never texted. I was a little worried I'd put my number in wrong so after some encoragement from my friends I added him on facebook. He accepted but never messaged me.. I never messaged him.

I really liked him and I'd be interested in persuing this, but maybe its a clear signal he's not interested since he never contacted me.

One thing that concerns me is that he is a bit older than me, and I'm worried that he is worried that I'm younger, and he doesn't want to seem like he's creeping on a younger woman or something, but I'm pretty down with it.

I don't know whether to just let it go, I keep thinking about it, I want to message him but I'm scared of putting myself out there again (after adding him on facebook already)

Can you condense the text into three sentences or less?
<bot>: I'm interested in this slightly older guy but he never made the move, should I make the move or is it a lost cause??
