This guy has only had one relationship his whole life. He is in his early 20s and finally ended it after realizing he "made a mistake" being in a serious relationship when he is so young and hasn't experienced being single. We met though and even he said being single isn't all that great and we had so much fun. We both just hit it off. Things went amazingly then he suddenly got flakey after we hooked up though we still went on a date after that. It made me think - what is it that makes a guy who wants to remain single decide to get into a relationship? Aside from the obvious things like a girl being hot etc.
