Break his heart.
Break him. Shatter it into a million pieces.
Let him pick up every tiny fragment and break his back doing so. He will cry for each stab of pain when he bends over. Let him.
Ignore his howls, even when they hurt you too. Steel yourself against his will, turn a blind eye. Be irritated with all his moves.
Keep walking forward and drown out his noise. He will cross you in his desperation. He doesn’t trust you. He might not have even known how to trust all his life. Forgive him, but walk on. Shed whatever power he has left over you, if there still is at all.
Break him further. Find peace and happiness. Break him further. Crush his haphazardly-repaired heart. Make him pick the shards up again.
For each time he bends his back and reaches out to the floor, painstakingly finding each piece to put back together, he becomes stronger, little by little. The time spent hunting is time spent reflecting on what he was, where he went wrong, where he was never right.
Every time he puts a fragment back, he will learn how to be what you always needed and wanted him to be. Except he cannot be that for you anymore, nor should he be. Keep moving forward, without looking back, so that he knows all of it, so that he knows he must take it elsewhere.
Make him realize, once and for all, that all he wanted was for you to be happy, even when it hurts him the most. Make him realize that he doesn’t deserve the one who breaks him, nor does she deserve him, for she will always deserve better.
He will understand. Trust me. It may not seem like it now, when his world is all bloody red from the pain, but he will understand.
He will understand it when his heart is finally put back together.
