Most Helpful Girl
It is hard to know why people know what they do. Maybe he has a boyfriend. Maybe he likes another girl and doesn't want to tell you. Maybe he just needs to figure himself out... I am really not sure on this one, but someone in their late teens and early twenties not "knowing" who they really are, is somewhat normal. I would have no idea why after that long he is just deciding that he can't be in a relationship, but here is what I say. Take it as a lesson, remember the good memories that you had, and if he is not contacting you, move on. There are other people out there who will treat you good, and not be afraid to have a relationship. Wish this person well, and mean it, and let them move on to figure out their life. You obviously know that you want a solid relationship, and they are out there... best of luck!
