Later I sent W a text about D13's school party schedule and she called to talk to me. She starts out sounding cold, annoyed, but I'm pleasant and thank her for calling.
I'm done fighting and being angry. I don't know THIS woman but she is the mother of my girls and I don't need negativity in my life any more.
And, on a side note, one of my projects which I was working on a really hard printing problem finally works today. Hurray for our side!
