For the everyday comments, swearing, etc., he does not apologize. He never apologizes to the kids for anything even when he really should. He is their master and they cannot defy him and he gets to say or do whatever he wants because he is in charge.
Oh I don't hear apologies for that kind of stuff either. If she said something inappropriate or that would hurt someones feeling it's always our fault for being to darn sensitive. I'm talking about the really really mundane stuff that nobody cares about anyway.
I posted this yesterday in another thread, I think, but when I called her out on her abuse (verbal), she replied, "I've always told you to stand up to me!"
No apology... . just her desire to have me meet her bottomless bucket of needs. In this case, the need for me to be her father.
