Yes you do know when enough is enough, I unfortunately stayed too long as well, have been so unhappy for many years &only happy outside the home & out of my husbands company, you do know as I do now, this life is to be lived & you only live once I have found the courage from somewhere & am scared of whats infront of me but truly know that there is more, than this constant barrage of abuse that still goes on in my life...
