I'll keep this one short, as I'm not well versed in this topic.
What is love, and why do we feel it?
I felt like I was in love when I was 18, she was my first serious girlfriend and it ended after 3 years. By the end I wasn't sure if I loved her. Since then, I've never felt 'love'. I don't even know if it was love that I felt for her, it was just that crazy excitement/nervousness that you feel at the start of any relationship. Then she was my best friend. Is that love?
I think love is really more of a choice than a feeling. I mean we (humans) can feel that excitement/nervousness for many people, but we choose to spend our lives with the ones we respect the most, or the most compatible, or the hottest, etc. I don't subscribe to the idea of a "soul mate".
So what is your take on it? How would you define love.. Do you think there is one person out there for everyone, or are we programmed to move on and 'fall in love' all over again?
