When do you find happiness

When you think you found someone that completes you.
When you think all seem so easy and happiness is just an arms length away.
Just when you think things could not be more perfect.
Then you see that it's not... All the while thinking things are OK.
When you feel so deeply, yet things still go wrong.
When you find something precious, then it turns to stone.

Why do other people ruin such feelings. Can't we just stay happy the way we are and stay together against the world. Whatever they present or put up to hold us back, let's go through it together.
I want you to hold my hand and have no fear, cause I will never let anyone hurt you.
I shall shield you from the storm and keep you warm.
Nothing to be afraid off cause I will be here to work things out.
