What is true love for you?

What is true love for you? In accordence with the movie interstellar ,my point of view is that true love is sincere , respectful.
A great example of true love ,is like the love that the principal personage has to his children,he loved so much   his children that  dicided to go space to save the future of the humanity but specially save to his children , he wanted a better future , sacrificing  his own life; I think  that this is the true love give everything for the people that really you love.
Other example of a true love is like the love of his daughter , she loves his father,  beginning  she suffered for have far his father, she did everything possible to rescue his father , she investigated  all for turn his father again to the land; Then she happed for many adverse things for to rescue his father ,she wanted to be near of his, such  way that she didn't think in the adversities.
For me this is true love to fight for the person that really you love , without thinking that could happen.
