We need to remember this.
It is only the people we love who can truly hurt us, for when we love them, we give them the power to hurt us. It is but unfortunate if they abuse that, for our hearts would then be crushed over and over again until a time comes that you no longer feel anything. When you become numb, it means that you no longer love them and only then can you really move on.
This is why we hurt the people who love us and we hurt the ones we love. Sad but true.
