You have to really love your boyfriend or girlfriend to have that kind of relationship. It's very difficult. Internet or telephone are not the same as you have the real person in front of you. One thing is not replaceable by the other. You have to really trust each other, you'll miss each other and you have to deal with it as you can. You will miss the contact, like hugging and kissing, as many other things. If you are in love, take a shot. Do your best and try to see each other in person as many times as you can. But I have to tell, the conventional kind of relationship is really better.
