What is Love?

Love does it come from above?
Love do you say it or show it?
What is true love?

My wife she’s the best she helps with getting my meds in order. She loves me no matter the mood I’m in. She is never changing or wavering. She of course isn’t God, but it seems her love never leaves me to. I have my thoughts and doubts of God and his ways.
My mom she loves me too.
