Love is to keep anything in you from destroying the heart of another. Love is guarding their heart just as you would guard your own. Love is protecting another's heart and doing whatever is necessary to nurture and heal it.
This is so true it hurts. I try so hard to hide all of my emotions and be happy all the time when my heart is breaking and slowly killing me. I try to be strong for everyone that I love even if I am crying myself to sleep.
