How Much I Love You?

Love is a feeling deep and strong,hate is the opposite;hatred is something we don't want.
Spectrum of feelings,emotional feelings is very comprehensive.But if we never experienced any of these feelings;how can we know when we were in front of them?or If we have not had some kind of experience in life,this means that we are lacking in empathy?
That we can not feel the same as those who had?
Feelings and emotions that we have,have different intensities depending on the context of the person against whom we have these feelings,the situation when we were.
Love is so complex,it has so many forms,but we can not say exactly when we feel or manifest for the first time in our lives;that for not being able to access memory from the first moment of our lives.
I don't think there is a specific age at which we can not love.Love comes,sometimes passing,then love comes again in our lives;intensity,frequency,consistency with which we love are different depending on each person.But that does not mean we are not normally able to love or to feel any kind of feeling
