Somehow, I am guessing that your W already knows most of those items on your list. It sounds too whiny to be begging. Show her you are strong by giving her space. You really should not send that as it is pursuing. Believe me, I was doing these similar letters and now realize to just "let go" and let her come to her own awakening. My W has acknowleged that what she is doing is so unfair to me, and now that I have backed off with the R talks and letters, she is thanking me all the time for things I normally do for the family. I have a long way to go and I dont know how it will come out, but I know she is going to give this time.
Your W has not filed for D. She must not have done it because inside her head, she has doubts. Let her work her thoughts out on her own and hopefully she will see what is right. If you continue to beg and plead, it will only make her more stubborn. Right now, you have time on your side. Get out of the panic mode you are in. You have planted the seeds of your desires already in her head. Let her have a chance to make them grow on her own. Just work on yourself and be the best father you can be to your kids.
It is too bad that you are the one to move out. I made my stand this last week and told my W that she cannot live under the same roof as me while she is dating other men. I had the thought briefly for myself to move out, but dropped that right away as I bought our house 6 years before I ever met my W. I feel good to have been assertive and I know that it is much better for my W to be out away from the kids so as to think this out better. She will hopefully have a desire to return to the good family life.
I will repeat a couple of things that I keep printed by my bed:
My marriage is over. I dont need my marriage. But I want my marriage. My wife is gone. I dont need my wife. But I want my wife.
