In this world the only thing we can be sure of is that, that we can't be sure of anything. Nothing lasts forever, no matter how we would like it to be. You knew about it painfully a lot. As time passed, you have found your hapiness. You have found person which showed you that it can exist in your life. 

In the blink of eye, you have lost it.

You were all alone again. 

And only he could become your new light in your life. Would you let him to be?
