TF,

Just a couple things:

Time & space are the only thing that are going to turn this around. She will never learn to miss you if you are around and available all the time.

You really have to watch yourself with your comments to the kids that the D and you not be invited to functions is your Ws fault.

Proof of what I always talk about women thinking emotionally. Logically she knows you love her, she knows the kids would be better off and she knows financially she would be better off if you are together. She didn't feel heard in the marriage like her feelings and opinions didn't matter that's why she felt unloved. That's why validation is so important.
