Kindachaotic made an important point -- children LEARN WHAT THEY LIVE. If your children (boys especially) see that women are supposed to be treated this way, then that is the way they will treat their wives. And the girls will choose aggressive men, who treat them badly. Children DO learn what they live.
I certainly learned WELL what I lived. I came from an alcoholic home, and I became an alcoholic. Yes, I learned well.
The trouble is, your self-esteem is in the pot -- I can tell that just by the way you're posting! Your words say it. Some time ago, I suggested a trial separation and I still think it's a good idea.
God bless my friend, and take care of YOU. Hugs, Lee
