my family is more important than my individual life so I plan to let this go on as long as she continues to be a good mother.
I'm very sympathetic to your philosophy, and have felt similarly, to endure a problematic marriage for the sake of my kids.
I'm not trying to dissuade you from that position. That's for you to decide. But I do think that somehow things will come to a head. It could be next week, it could be months from now. In the mean time I hope you maintain your own emotional health and your integrity and dignity. And when things do boil over, I hope you will be as emotionally prepared as you can be.
