Tad, 25 said it all...why would you even think about taking your wife back right now, especially w/the way she's been acting towards you? The woman you knew is gone and has been gone for quite some time. She emotionally left the marriage long before her final exit. If and when she grows up, she may not even be the woman you want back in your life. What if she doesn't grow up and remains a mess? Don't put your life on hold, hoping that she will come back to you the way she was pre-mlc.
Yes, she's miserable. If she weren't, she wouldn't be consumed w/what you are doing, calling you, making comments to your children and the one thing that says it all...she knows about your dating, etc. If she were happy w/her life, she would go on w/her life and act like a mature adult and at least meet you half way in co-parenting and not be making such comments to your children.
Tad, enjoy your life, you've been given the opportunity to start a fresh w/your divorce. Give your wife's situation to God and allow him to take care of her. I know it's difficult, but you've got to stop analyzing her comments and behaviors because mlcers change on a dime and give you 9 cents change. They are emotionally a mess and no one can operate on pure emotions full time.
Tad, it's time to take care of you!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
