I am concerned that why did guy or girl move on to find another someone else after problem with someone else?
I notice most guys or girls decide to go back to same person whom like them before, they know person who like them, too. It time after not decide to move on to find another someone else. They believe someone else is right for them, not another. If he or she find another someone else, it will something bother them or notice someone else is not good for them. They had feelings with someone else before.
