I think I'm in a smiliar situation. Me and one of my guy friends dated for over a year, then he ended it. The relationship was never serious, and it started out on the presumption that it was just a "fun, little high school thing". No sex, either. He ultimately decided a few months ago that, since our relationship wasn't serious, there was no point in it. He wanted to live the single life, I guess. We remained friends - one of our little pacts before the relationship - and I thought I was doing okay, until I started going over what he said were his reasons for breaking up. It just didn't add up, at least not to me, and that rejection feeling started to sink in. Then this girl who's after one of his friends started hanging around all the guys. And of course, I'm super sensitive to the fact that she's become all the guy's new best friend - including my ex's. I always swore that I would never be one of those girls that get into a huff when they're ex's start showing interest in other girls, because, hey! - they're ex's. But, friendships after relationships, no matter how "light" the relationship was, is harder than hell. When they work out, thought, they're a wonderful thing, because you have a friend who knows you better than anyone could ever.
