When working through the details of our parenting plan, she played the "family law" trump card and let me know I would not be getting 50/50 parenting, because if she went to court she knew she would win exactly what she wanted.
My ex-wife screwed me in the divorce and she and the therapist that setup our 70/30 parenting plan knew it. They were not basing their plans on science, but on "what's best for the kids" mythology that has been perpetuated since my parents got a divorce 49 years ago.
And so, I've been girlfriend free since the end of the summer and it's fine. I'd rather not be. But I'd rather be alone that coping with another person's major emotional distress. I don't need drama or high theater.
