what is love

what is love？
i often think about this problem.
But i do not have a exactly answer.
Maybe is a thing that you can pay life for others.
Love is a kind of giving.
If one person who can not give ,
he must do not know what is love.
I am a young girl.
Maybe some people may think i can say this problem.
But in fact ,i have experience many things.
My parents got divorced when i was very young.
Because my father fall love with another woman.
i can not understand.
Why they were became now.
My mother and my father have love when they were very young.
Even i can say my mom help my father gone with the time that was most terrible.In that time ,
my father had nothing.
No house,no money,no car,no money,he was very poor.
But my mom followed with him,just for love.
But what he gave my mother.
After he have money ,
he have another woman who is younger and more beautiful.
And at last ,
he even for that woman desert me.his dauther.
I really do not know what is love.
Love is so changeable.
From my parents' love i learn that one must keep himself in love.
Once he lost himself ,
his love will lost too.
