is LDR enough to get to know someone.

I fell in love with my best friend. We were friends for 10 months, and spent everyday together. We are now in a LDR. Having him leave brought attention to the fact that neither one of us, want to be apart from each other. We want to be together, even if it is only over the phone, I can't imagine him not being apart of my life. Our "relationship" is still new, but he is an extreamly important person in my life. Now....we are trying to find a way for him to move to live near me, because he loves my state better then his. As we are both in college he would like to continue his schooling. Out of state tuition is expensive, and we are afraid it will be almost impossible to pay for it. We don't know if it will be possible for him to return until he completes his degree this means we will be LDR for 2 years before he returns. After two years of a LDR would it be feasible to get married? I know it is a long way ahead, but he is already talking about it. I personally think it is important to date while in the same state together for a year or two. Having someone face to face is different then over the phone. What do you think?
