Also realized I forgot to address the issue with her health and the kids health.
My W has told me repeatedly that she "loses her mind " when she has the kids on her own, and I worry about what may happen if they are alone for extended periods of time. In fact, the majority of our tension happens around her scheduling with the OM I.e trying to get her time away and then feeling guilty (mind reading sorry). And when she has the kids on her own, without the nanny and she is overwhelmed and then turns on me irritated and furious.
She often lashes out at the kids verbally. I have all my text conversations on file. The only reason she wants increased custody is for the money. If they are with me, she would have to pay me support, and she can't afford to. They need their mom, and they need their mom to want to be with them.
