Even if you love someone so much, with all your heart, sometimes it’s best to just let go however painful the results may be. So when is it proper to let go? I guess letting go becomes proper when you have already shown how much you love and value a person and still nothing happens or you’re not loved back in the same intensity. It becomes proper when you know in your heart that you have done your part but your efforts were never reciprocated.
Letting go doesn’t necessarily mean giving up on your feelings for a certain person. Sometimes, it is just a matter of choosing to love him/her from afar, just from afar, to save yourself from further heartaches.
