Pay no mind to what she says. It is all fabricated. She wants to be separate and free. She has this idea that the grass is greener. It is not. She will use her fabricated stories to justify her destination and her gas-lighting and spew to convince you. Listen, validate but treat 100% of everything she says as a lie - it most likely is. A lot of what she does is also. She will rage and spew if she can not get you to follow her lies, due to frustration. Stand firm.
This is a sh!tty time. You just stand firm. Don't let her get in your head. If she is exercise to get her out. Then keep her out. Forget her as your W, you must stop wanting her (as she is). You need to see her for what she has become, not what she was. Let this new person go and then decide if the old W can come back. She may not.
You are being an amazing Dad. Remember that. Be the best version of you for your D, SS and you. The crazy one IS NOT YOU!! She will try to make you feel like it is. She has perhaps learned this behaviour. Stand strong matey!!!
