yay for movement on the geometry front! That's great news!
I just wanted to make an observation about your W... one perhaps you've already made.
I think a lot of women struggle with knowing the difference between self-care and what your wife is doing which is not giving to anyone so she can care for herself. These are two VERY different concepts but fed up people sometimes get them confused. Self-care is our responsibility so we can take responsibility and fill our own wells so we can continue to give. The other is selfish and devastating to children (and spouses, clearly) and gives the impression that the only person who matters is the one who doesnt' care anymore. I think your W *thinks* she's taking care of herself in a healthy self-care kind of way but she's missed the point entirely. She's emotionally abandoning her children and a part of me feels like she's not seeing that like she should. That's frustrating for sure.
Keep being the involved and in-the-know dad. Keep communicating well with your kids and being grounded. Your kids need that a lot.
