Why is it more sad to come back from a lovelorn trip?

There are two tendencies to travel after being lovelorn, one is to relax, and the other is to escape from reality. Many things will be over when the rest people go out for a walk. People who escape from reality will put it down for a while, and when they come back, their hearts will be more empty. Alas, anyway, feelings are everyone's heart, and only they know how to open them.
