He Has Shut Me Out of Our Relationship

It’s been a year that I have been in a relationship with my bf, we live just one 35 minute plane ride away from each other. I had him in my community for 1 month, then he finally went home, and suddenly after a couple of days, he shut me out and he won’t tell me the reason why. I kept asking him what the reasons are, he said distance was one of them, and he wouldn’t tell me the other reasons. I gave him many chances to be with me, but I’ve got only very few chances from him. Is he worth the wait? Will he open up to me and everything’s back to the way it was? It’s been almost two weeks now that he has shut me out.
