I have done a pretty good job on focusing on me, and I have given up caring what she says/thinks. As long as something is the right thing to do for my kids and me, then that's what I do.
Yesterday was a blip caused by what I perceived as simply rudeness and selfishness on her part - I know I should not be surprised by that, and I'm not. Just think it bubbled to the top.
Despite my feelings yesterday, I do still feel things moving in the right direction overall for M. We will just have to see where it goes.
