That said, remember that you can't change anything about this. You can't save H. That will be up to him. You can only decide if you'll take him back.
Think of Mother Theresa, she would say whatever she had to say in love, but she was tough! People would come to ask for prayer advice and she would hand them a broom. Say what you need to say in love. If you think he doesn't know that you are standing, you can say it, once.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
