shirurinu,
sad to hear u suffered so much in this relationship. there were time i caught u crying over the phone while talking to him, but dunno how to console u..

put urself into his shoes, he himself lack of confidence because his gf is pretty n he afraid that one day his gf will change her heart and leave him... somemore both of u have little time for each other due to ur work schedule and his...
but ask urself tis question? should u both maintain tis relationship, does he breaks ur heart for saying things which hurt u most of the time?
long-term suffering is more worse than short-term, whether to end it is up to u, the choice is yours. just remember if u feel down, u can pour ur sorrow out here and we will try our best to help u.

sometime it's better for a couple to have trust and understanding for each other, be it a long-distance away... it's nvr easy though...
song to recommend to u to listen:
i don't wanna cry by mariah carey.
