Distance clears up

At the distance some things seem to be more evident than at immediate consideration. It happens because at the distance you see the whole situation but not its fragment.
When a person you love goes far-far away you start feeling such an overwhelming love that it's too difficult to cope with it. What's more people's vices are also become more evident. So it can be a kind of a therapy to move to another place to understand the core of something or somebody.
