How does it last?

How does a relationship last when both parties are in a long distance relationship (hereafter, known as LDR)? How does it last when he only calls once a day? How does it last when each call last only 3 minutes and both have to summarise their whole day in less than a minute? How does it last when he wants to call only once every 2 days because of the expensive phone bill? How does it last? Can somebody please tell me what to do?

Even though we started our relationship as a LDR thing, it's been ages since we were apart for so long. And the fact that it's gonna stay permanent as long as I study in KL and will only be back in Penang during my holidays doesn't help the longing in my heart for him. I miss him so much...and he promised long ago before he left that he'll be down in KL for a day or 2 just to see me. BUt once again, he's going to break that promise. A promise that I look forward to for weeks. He had not confirm anything yet but deep down inside, I know he won't make it. Yet, my heart hurts. And I don't want to hurt no longer. I wonder how it'll be when I leave for Perth end of next year.
