What is the difference between love based on needs and true love?

I think we are all human beings . we have our own desires.
It's certain that some of the desires or needs can be fulfilled by love,
probably only be. This partially attributes to the greatness of love ...
We are intrigued or fascinated with love due to the happiness through fulfillment.
True love can not always let you feel fulfilled, it comes along with pains, sorrows,misunderstandings,arguments or somethings else. Only by overcoming this can you tastes the true love. And at the same time, it's crucial to let your beloved fulfilled too,so we need to learn to pay,to sacrifice.
Happiness is mutual!
I think at this point of time, the fulfillment is in a diffent level,and the love can eventually turn out to be true!

true love is love that is unconditional, it isnt based on needs,a the love that is just for fulfillment of needs is not love, its just lust, and selfishness
