Yesterday, everything was wonderful because he stated his desire to work things out and be happy with you. Today, you forsook the NY Times for the Daily Snoop and everything is awful. Your brain (with a little help from some hormones?) is trying to kill you.
Detaching isn't about distancing. Think differentiation. Not taking things personally. Loving detachment.
Do the things you can do (did you get legal advice yet?) and let go of the rest. Do some more meditative yoga. Peaceful, happy vibes.
I've never been a big fan of parental (not a typo) rights. The implication is that kids are property. I think parental responsibility is a much bigger issue. You never see anybody drag their butt into court demanding to be allowed to pay doctor bills and stay home with a sick kid and on and on.
Okay, enough rant. Back to peaceful, happy vibes...
