What Is Love?

In case you didn't see it last night on 'The Bachelor', Jason was convinced that he had found the love of his life and he proposed to her. Later, on the 'After The Final Rose Ceremony', Jason dumped his fiance' in front of millions of people on live television and then proceeded to run back to the runner-up in the competition in a successful attempt for her to take him back. Needless to say, it was some classy television.

On a serious note, it got me thinking about love. Not puppy love or 'I think I've been in love before' love, but actual true love. What is true love? How do you get it? How do you sustain it? etc.

Most people would say that being in love is a feeling. I have a really hard time buying into this because feelings come and go. There is no stability in feelings. Emotions change with circumstances. I think most everyone would agree that true love is unconditional and it seems like there are too many conditions for love to be an emotion.

The only conclusion I can come to is that love is a commitment. A commitment is stable. This commitment can be accompanied by romantic feelings and passion, but the commitment is not dependent on them. Commitments don't change with circumstances. It seems love has to be a commitment. 

How do you define love? What is love? What is love not?
