"Wife, I understand how you feel about our communication problems, that you feel beat-up, and that you feel you haven't done anything wrong. I also understand very clearly that you believe I left you, our marriage and family last fall. I accept total responsiblity for that and I am both sorry and aware of what I have done to you and our family. Given a second chance I would spend the rest of my life making it up to you. If you believe that divorce will make you happy then I accept that. I cannot stop you from divorcing me but know that I want you, my marriage and my family back."
Yes, it's pursuing and a R talk. You validate her, you apologise, you accept responsiblity, and you make it clear of your position. Once you say it don't bring it up again. No more e-mails, calls ,txts. Your actions will do your talking from now on.
Make sure you understand her frustrations, issues and beliefs. You dug a hole now stop digging. What did she tell you she wanted that is good for you?
M22,H45,W45 S21/18D12 Retain faith that you will prevail in the end, regardless of the difficulties and at the same time confront the most brutal facts of your current reality, whatever they might be.
