Shall I contact him, or play it cool?

I feel a little bit immature asking this, but I’m having a hard time making a decision! Recently sparks have been flying between me and this guy from my course at uni. We’ve had the ‘I like you/ I like you back’ conversation, but I said I wasn’t ready to get into another relationship so soon from getting out of another (got out of a year and a half relationship a month ago) – and he said he’d wait as long as I needed. But obviously as we spend so much time together it’s makes it more hard and awkward by avoiding anything romantic, when it is so clearly there. Anyway, last week we both left to go home for easter for a week and he kissed me before he went. I was quite awkward about it, even though i reeeally like him, just because I was worried about rushing. Now I’ve had time to think, I think the right way to go would be to stop trying to avoid ‘the relationship’ label, and just go with the flow and take the relationship slow… instead of trying to keep to the friend boundary any longer.
I haven’t heard from him since the kiss happened, and I’m not sure if thats because he wants me to be the one to contact him or because he thinks he should just leave me alone for a week until we get back to uni… or if it’s because he’s decided he doesn’t actually like me. I’m aware I’m thinking far too much about this! but please help should I text him? Or should I wait for him… And even if he doesn’t contact me should I just wait to see him when we get back to uni? He’s made a lot of the first moves and this is the first time he’s held out from talking to me, so I’m just not sure what to think/do. I’m so rubbish with this sort of thing. And I really don’t want to come across as clingy, but I think that because I’ve been worrying about this so much I may have come across as the opposite… I just don’t want to mess this up!
