There are many different forms of love. Love of children, love of parents,romantic love, sexual attraction is a form of love!
Some love is instinctive, and is why a mother will throw herself under a bus to save a child; maybe not even her own child!
Love in all it's forms is not taking; it is giving.
Probably Jesus gave the perfect definition,
"Greater love than this has no man, than that he lay down his life for his friend."
Please note, not parent, child, or other relative. "His friend!"
That says it all!
