Personally, I now find being around people throwing "temper tantrums" unacceptable for any reason. It is amazing to me now how I used to make excuses, justify or minimize unacceptable behavior all under the guise of being supportive and loving.
My husbands drug problem was not mine, it was his and his alone. Under no circumstances, should I ever have allowed his consequences to his choices in my home a place a refuge or my life. But it took a while before I finally grasped that. My own fears, obligation and guilt kept me stuck and in a fog.
