If I were you I'd just ask him! Had a similar situation with a Girl recently, actually kissed her on a couple of nights out so I was really thinking maybe there could be something proper. Ended up just letting it go for a couple of months and then eventually decided screw it I'll just ask her. ... I'd love to say she said yes and we're together now but that didn't happen! But felt a lot better knowing how she really felt rather than leading myself along any more. Still good friends now though, neither of us made it awkward after. Just my own personal opinion/experience.Good luck with whatever you choose though!
