The definition of LOVE is............

Love can be defined in many ways, but i think that it has no definition.
You can get married to someone for twenty years and up and it still doesn't mean you love someone. You could see a gril that you like aand have butterfly's in your stomach it still doesn't mean that you have love for someone. What is love?; can anyone really truelly love someone, and will your so called love cause you to put your life on the line for someone: will that be a sing of love.
