Try to move your mind to taking care of you. And the kids, of course. Try to allow yourself to be in control of your own emotions, rather than letting his actions determine how you feel. Try not to be concerned with making him happy. Right not you can't, and you can only drive yourself crazy trying. If you pursue, he will pull away harder.

You are in for a long ride, one way or the other. But you can come out of it stronger, better, and happier.
