Time to drop the rope, and move on down the path, TMB. You've made a yeoman's effort. Divorces take time to finalize, and some couples reconcile later after divorces are final. She may come to her senses when she is served, she may come around the night before your divorce becomes final. She may come to you a year or two AFTER the divorce is final, having grown, and maybe you are each in a different place then.
Or she may never.
You will be fine. I could hear it in your voice last nite.
She is a weak, foolish, stubborn woman, and she needs help. She is drowning, and you were willing to throw her a life raft, encourage her to swim, and even to show her how to do it. But you can't RESCUE her, and at some point, if you cling to her, she will pull you down with her.
We can't tell you what that point is. I always told you you'd know it when you reached it, and this is why I encouraged you ahead of time, in a calm moment, to decide how many "strikes" you were willing to put up with.
