A guy who is way to cocky and thinks way to highly of himself. A guy who is afraid to commit to the one girl who has never let him down, even though he said he regrets not being with her. A guy who will tell you he feels one way and then the next day he will change his mind. This guy is also a complete smart ass and can be a dick. A guy who will regret ever letting a certain girl out of his life because he wanted another person.
A guy who could be great, but holds himself back.
Wow, that guy did that to her? He has to be a Dustin.
