Continuing DBing

[PeterV2]

She said she would go NC.

I need to bring it up again and tell her I'm not willing to live in an open marriage. You said you would end contact. I need proof of that. Here are 3 versions of a no contact letter I've prepared or you can write your own, but I need to approve it before you send it to him. And then I need to be able to see you phone and for you to open up your computer to me. If you're not willing to do that then it's over between us. I'll get a mediator involved to hammer out the terms of separation and divorce. - Maybe a little aggressive, but definitely stating my boundaries.

Here are the letters. I'm thinking of sending them to W in an email so she can edit them and send them to OM. Or write something in the same vein.

1.
I have made a decision. I want to be with my husband. I no longer want to continue our relationship or keep any secrets from Peter. Everything is out in the open. I realize now that I used poor judgment in getting involved in this in the first place and am sorry for that. I plan to get help to understand how I could betray my own values as well as my family.
I am recommitting to Peter. Do not contact me again for any reason.
I know this is abrupt but that is the only way. We both knew the risks we were taking. Please respect my decision to no longer have any contact. I will no longer respond to any email, text, calls or other attempts to communicate with me.

2.
I want you to know that out of respect and love for my husband, I have come to realize that I must never see or talk with you again. My relationship with you was a cruel indulgence that Peter did not deserve. While I cannot completely repay Peter for the pain I have caused him, I will do my best to become the wife he’s been missing. I care a great deal for Peter and I would not want to do anything to risk his happiness. I will not make any further contact with you and I do not want you to make any contact with me. Please respect my desire to end our relationship.

3.
The relationship I had with you was thoughtless and cruel. It hurt many people, particularly my spouse, who did not deserve to be treated that way. I am committed to my marriage and determined to make up for all the hurt I’ve caused my family. I am going to work hard to be the best wife that he deserves.
Because of the terrible offense to my spouse and the damage I have done to our marriage, I am permanently ending all contact with you. Please respect my wish to regain my integrity, and to heal my family. Please also respect my wish that you not attempt to contact me in any way at any time.
My spouse has all the details of our relationship and he will also be told of any attempts at contact.

She will of course saying I'm being controlling. I'll just say I'm only trying you help you find the words. You can write your own as long as I approve it before you send it. And if you're not willing to do this then I know it's over between us. And I'll be ok with that.
