stopping now is the best gift you can give yourself, your wife and daughter. Good on you!
yeah, that invisible guy. He's gone now, you might find yourself mourning him for awhile, for the "good memories" and there probably were some, but we find out we move on, and it IS a huge relief to have the pressure and insanity of an abusive relationship out of our lives. More energy for the good stuff.
You've come to the right place. Glad to have you.
