to have means ready to lost

when you meet someone, there always be a time when you must said goodbye.
when you loved someone that means you know what is the mean of love.
when you have someone to share u'r life means that you ready to lost him/her.
when you lost someone means that god is planning to greet you with someone better.

but sometimes we don't understand why we love someone.
but we don't ready when someone we loved left us.
and when we lost him/her we don't thank the god for the oportunity that god gave to us.

people said that love is blind, love doesn't need reason, love is the matter of feelings, etc.
but what is the mean when u said "i love you" to someone?
are you understand?
i don't......
