Poor woman! Doesn't she realize that love is not divided, it is multiplied. When we are born we have love for our parents and love for our siblings. Later, we may develop love for a spouse and still later, love for our children. With each generation, the cycle starts again.
When a man and a woman get married, they don't give up their love for their parents. Nor do they have to share their spousal love with either their parents or their children; because each type of love is unique and independent of the others.
