I theorize that the saying is true because based on my own experience, I feel very lonely when I miss my guy so much, when many days pass without us seeing each other. My anticipation of seeing my love again, gives me much happiness and excitement. Love is sweet when two lovers are together, walking hand in hand, sharing stories, feeling each other's hugs and kisses, but when they are away, and thinking about those sweet and romantic moments almost make them crazy, crazy in the sense that they will do anything, everything just to be in the company of their loves again.
Going back to my theory, the saying "absence makes the heart grow fonder" means that "love can stand the test of time." It feels very sad for two people in love when the time to say goodbye comes. They will have to let go of each other's hands, break free from the tight embrace, and go their separate ways with a kiss. The saying "absence makes the heart grow fonder" starts with another saying, which is "parting is such sweet sorrow," because one will only feel the absence of someone she loves when they part ways. Yes they will say their goodbyes and be lonely for a while, but the thought of again seeing each other is what they are thinking of. Lovers are always like that. The absence of the person I love most will only make me miss him more. People who love by heart know that.
Moreover, the greatest opposite of being with your love is being far away from him, of course. But what distinguishes these two dimensions of love is the feeling residing in the faraway hearts is their feelings. When I am with my love and holding him close to me, all I could do is to cherish the seconds I am in his arms, because those moments are the ones that will be forever remembered, especially, when he is not around and I am missing him badly. And when I am feeling sad because I miss him, all I would do is close my eyes and reminisce. Those thoughts will serve as strength in the time of waiting for the time of being together again. This saying not only applies to two persons in love, but it can also be true with a person missing someone important besides his significant one, or it can also be applied to a person feeling the "absence of a place, of an event or even things." (Hirsch, Joseph, & JamesThe New Dictionary of Cultural Literacy, , 2002). But of course, the greatest of the three is the fond heart that misses a person, for loving a person and being loved back by the person is the greatest feeling in the world. Missing someone could not happen when she is always with her love, and that means, for their bond to get stronger and her love gets even more intense, because it is waiting to come out and be showered upon a loved one.
"Separation makes love even more intense" (Answers.com, 2002) that it normally is, distance triggers the want in two persons to be in each other.
But much-prolonged absence can mean something else. It can lead to the loss of hope, excitement and the disappearance of
