When someone you love hurts you, that is a knife in the back. But when that someone hurts your kids, it is hard to hold back the rage.

Lost, dont ever doubt yourself for any of the blaming your H is doing now. You are the one working 2 jobs and being the foundation of a rock for the kids. I worry that your lack of time for any fun will cause you too much stress. By all means, go out an enjoy some platonic fun once in a while.
