When me and my ex-girlfriend went to different universities, we were living on different islands. Certain things made it impossible to keep up a relationship. I didn't have any direct access to a phone, so I could hardly ever call her. The realtionship had diminished to almost only ever texting each other. That kind of non contact wasn't enough for me so I broke up.

Point being, that sort of relationship is not for me and I would probarbly never try one, but If other people can do it, and it has been proved possible, then I have no problem with it.
