The issue in LDRs is mostly lack of intimacy these days, since you can easily be connected all the time.

I'm not sure you would need this from someone in sales from company X.

As you say the problem would be _building_ relationships, which is different from _maintaining_ them.

People have been leaving their parents' place for a very long time, but this rarely means become estranged, because the relationship is already there, and it's not that hard to maintain.
