why love hurts?

Love is wonderful but why love is so painful? Why we always hurt by the people we love?
Hurting by the people we love is very easy for them …….so we reach to a conclusion love hurts. You do everything to ease the pain but nothing helps nothing can make this easy.
The Basic rule is the more you love the more you hurt. You hurt because you love…………. what a painful punishment. You try everything every idea to keep the person you love but nothing changes, nothings helps.
When we truly love someone we worried about them worried about what could happen to them when they are away and we stay all night and wait for them come back.
I think that is not love that hurts
Every one of us needs to be loved, even those who pretend that they do not need love in their lives. And when you separated with the person you love you begin to feel depressed and all negative feelings in the world.
In that moment everyone think that the quickest cure is to get involve and find another love.
And these step will make you more miserable.
