CC,
Was that the whole of your way back to the marriage requirements? A NC EMAIL (not letter you approve and both mail by hand), changing her cell number and not allow texting?
I ask because MC/IC is a usual step in the recommitment boundary...provides a third party right there for confrontation of just this stuff. Doing the homework for it, etc.
What about her changing her email addresses, in totality?
Plan B letter lays the way...cannot protect you entirely...says boldly, "I know you choose your life. I hope you'll choose our marriage...if you do, these are the steps leading to recovery I need BEFORE" you break out of your dark Plan B.
I understand the disappointment, hopes and fears you have right now. Hard to accept, helps to remember...it took YEARS of a wayward mindset to get here...why wouldn't it take years to heal?
I vote to continue to verify, whether you've caught all her lies or not. That's your province...to patrol your marital boundaries and to verify no contact (NC). Your truth isn't in HER hands...to put it there is nutsy. My WH broke NC a few times before real recommitment...takes time. I verified to know the truth...my job. He began telling me of contact later...and has remained true to that, even through third-party info, for two and half a years. He didn't forget that promise.
People do change.
Rather than two choices...sit back and watch or confront...how about state The Truth. "I know you lied to me. I do not choose to believe you are being transparent right now. Did you want Chinese or Italian tonight?"
Owning what the truth, separate from your truth...well, that's your half, isn't it? No explaining what, how or why. "How did I lie? When?" "I know you know. I respect you chose to lie and I'm sharing with you that I don't believe you right now."
Amazing how learning we can have a marriage without trust or believing in the other for awhile...that it exists and we can live without it, when thought it wasn't possible.
If you want to live from truth and respect...act from love...then your choices are clearer...you share truth. Just like with exposure...so you don't sit back and watch...and you don't confront (can't make her unlie and you already KNOW she lied, so admission makes no sense)...so own what you know...share your thoughts, feelings, beliefs, perceptions and perspective...no LB's...calmly...and stay O&H with yourself and others.
Best road to recovery I know. You've lived through so much already, CC...choose your perspective, your life premise...your code...and stick to it. Focus on your own personal recovery, ephiphanies, growth...no sitting back and focusing on her stuff. What are your predetermined progressive boundary enforcements in the event of contact (which crosses your boundary of contact continuing the affair)? You verify for your marriage and yourself. Your job, 'k?
