What is love?

Preparing some presents for my daugher. I end the letter with " Lots of love".
What is love actually? Love is giving not receiving!!! Love is from your heart not from your mouth!!! Love is your action not your saying!!!
I love P so much. My friend said to me P will never know I still love him if we do not communicate. But I know I did not cheat myself, I know and told myself that I do love him. He does not want to to contact him, okay, cause I love him, I will not do so. My friend said this will bring me more pain. I know, it's very painful by know and watching him be with some other girls. But love is giving not returning, so I do not feel guilty to just giving my love.
Love you!
