Sounds like a similar problem to what I'm having. The girl I started seeing not so long ago stopped communicating with me as much as she was, almost didn't seem as enthusiastic if you know what I mean. Mind you I became a bit timid and shy after *that* first kiss situation. So the guy you're seeing could just be frightened of saying something stupid or upsetting like me. Think that happens to a lot of people when it's clear that they are actually 'seeing each other'. I'd give him a bit of space, but still keep in fairly regular contact, drop hints that you still like him etc etc, because you don't want him to think that YOUR avoiding or ignoring him do you?! Well, that's my opinion. Don't happen to know what's goin on if a girl like yourself stops being as communicative towards the guy they are seeing do you?
