Most Helpful Guy
Maybe he needs more time to really understand what he wants in life. You should definitely try to talk to him and try to fix things.

Move on. What's there to fix? He's not ready for a relationship, and that hasn't changed, so there's really nothing to discuss. You're better off not staying in contact and being friends with him (which never really works since feelings are involved) because that will only make it harder for you to move on. Which you need to do if you want to find a guy you're just as great or better with who also does want to be in a relationship with you.
