Do you really need to seek more love outside your family?

A loving, happy family is a wonderful thing to have. But there are different kinds of love. I Love my Mother, Sister and kids etc. But I am not In Love with them. It is both normally and healthy to have a Love outside of the Family, someone you can be In Love with and have intimate relations. I also love my best friend, but again it is a different kind of love than what you have for your Family or your Partner.
