I asked him whether he just wanted to meet in the park, without having to spend anything. No response. Asked him again today, he logged online, went back offline.
I unfriended him. Not because of this, but because I want someone more straightforward than he is. He could be perfectly nice. Just not for me.
Better luck next time. 
Thank you.
Well...this was the first message I sent him:
Hi Chris. You may remember Joey mentioning me a few months ago, I said I needed some time. I just wanted to clear up that I didn't know you knew about me...in other words, I took Joey literally when he said he'd mention me to you once I'd sent him a photo of me to pass on. I didn't know he mentioned me to you. I feel it's relevant cos I feel like I've appeared really flakey. It really wasn't intentional, if I'd have known you'd known, I wouldn't have kept you waiting like that.
I'm not sure what Joey has mentioned. For some reason when I enquire about you to Joey, he thinks I enquire too much, though to me I've hardly said anything.
But anyway, I hope you can see that I wasn't rejecting you. All the best, justcurious.
..
That's it. I was starting to really like him, even if we did speak practically different languages.
