Dear ex:
I am currently doing my best to continue meeting Jehovah's standards for morality. I find it very disconcerting that you are hopeful that I would incur Jehovah's displeasure by committing some form of immorality. I wish no evil upion you and find it bothersome that you would hope that I have sinned in order that you may join with someone who is not your husband.
I am almost of the opinion that you have already sinned within your heart.
I have been faithful to the expectations God has for me in my current state and feel it only appropriate that you too follow the same path. However should you decide to disobey Jehovah I too would appreciate recieving a letter from you advising that I am free to remarry."
I pray that you respect Jehovah's arrangements and hope you find the joy and happiness that comes from following Jehovah's laws rather than succumbing to the needs of the flesh.
From you.
Then go screw your brains out and enjoy living.
