Doodler, Something you need to look at, in your own progress: why did you pick your wife? Why did you think a woman with a serious mental illness was an appropriate choice to be the mother of your children? Was there something familiar about that dynamic from your childhood? Or something about your self esteem that you thought this was the best you could do?
I'm not knocking you or your wife. But in order for you to make healthy choices in the future and not repeat this pattern, you have to understand what led you to ignore the red flags.
