Advice please - male perspective welcomed!

Ok, Im going to skim over things otherwise I'll be here all night.

I've just split up with someone - well he told me he didnt think he was ready for another relationship. Normally I would consider this to be a line. However in this case, he married young and got divorced a year or so ago - I know the divorce was hard on him (there was no affair or anything, but they argued alot). He asked me afterwards if we could remain friends and see what happens. He also said that he missed seeing me. So anyway, I replied to him saying that maybe we should just meet up for a drink, as mates. He replied straight away saying yes and we said we would sort something out for next week. Next week comes around and he said he had a stag night or something on that he'd forgotten about and could we make it the following week. I thought that he was messing with me and asked if the 'friends' thing was all talk. I wanted to know because he suggested it and had been all for it but didnt seem to want to follow through - I mean a stag night is only one night, not the whole weekend. I had this feeling that he wanted to keep me on hold so to speak and keep me in his life until he was ready to decide what he wanted, and I didnt really want to be his back up.

Problem is now I havent heard from him and If Im honest, I do miss him. We got on great and had such a laugh together (and slept together).

I thought maybe I should just give it a month or so and then just call casually and ask how hes doing - If we had not been getting on then I could understand more, I know his divorce knocked the stuffing out of him but it cant be just that can it?

I know after his divorce he briefly dated another woman on the rebound.

What do you think - give it a bit of time or move on now?

(btw Im 22 and a student nurse - he's 28)
