The Student Room Group

what shall i do ?

So basically, theres this guy who im beginning to like once again... around this time last year we had this 'thing' but both decided to end things. Since then we have been able to get to know each other better - but as friends, we are part of the kind of group ...
Sometimes i get the impression that he likes me too ... he changed the subject when a friends asked him how he felt about me. I'm not to sure what to do, confront him or just leave things be, i don't want things to become awkward between us.. what do you think ???
