We fall in love with somebody not because of who they are but because of how they make us feel about ourselves. They are attracted to us so therefore we suddenly feel very attractive and grow in our self-esteem. The more they are attracted to us the better we feel, and the better we feel the more we are attracted back to them for making us feel this good. In turn, they feel the same feelings and emotions as us because we are making them feel good about themselves, too! What a great cycle of love: we actually fall in love with each other for making us feel so great about ourselves.
