Thx WhatNow. here is the new version

Dear Mr. 4luv,

I love you and I married you for life. I want to remain married to you. I am willing to address the things that I did wrong in our marriage. However, your recent dating and past affairs are painful and to protect my feelings for you I will not have contact with you while you are engaging in that activity. As soon as you stop your painful activity and you can assure me that the past affairs are over then we can talk about our future. Until that time please respect my wish to not talk to you.

In an emergency you can reach me through text. Arrangements for seeing children and handling finances can be handled via text or email.

Sincerely,
4luv
