Agreed, to love someone is to be willing to give all of yourself to them simply because they are more important to you than you are to yourself. Being around that person, just spending time with them, doing nothing at all can make up for the worst of times. Holding each other, not saying anything, just glad to be together, realizing that this is all you really need.
As much as I have tried to describe what love means to me, to me love is one of those things that can't be explained and can't be described. "Words can never replace feelings, nor pictures replace having been there".
FallenOne, your thoughts reminded me of this:
"To love is to suffer. To avoid suffering, one must not love. But then, one suffers from not loving. Therefore, to love is to suffer; not to love is to suffer; to suffer is to suffer. To be happy is to love. To be happy, then, is to suffer, but suffering makes one unhappy. Therefore, to be happy, one must love or love to suffer or suffer from too much happiness."
--Woody Allen (American motion-picture director, screenwriter, actor, and author,1935)
