There are both selfish and selfless aspects of love. When you fall in love with someone, you want them to commit themselves to you alone, and to share their entire life with you. At the same time you'd be willing to share your own life with them and do anything for them.
Love is the meaning of life that was never defined.
The way I do it it sure as hell is! . . . :)
I'm not going to look at your link because I already know love isn't selfish. It's really more selfless since it's shared. If it's only one sided, it's not love at all.
