Abuse of any kind, whether it is drugs, alcohol, domestic, sexual, etc. The experiences my children shared growing up in our home and the example we set for them were carried into their adult life. My daughter married a man who is a carbon copy of the way I used to be. He is abusive, alcoholic, and controlling. She is now going through a very painful divorce in which he is still trying to control her actions and reactions.
Abuse is a family disease and it needs family treatment.
Please, remember though that the abuser will not stop on his or her own. Place distance between you and the abuser. Treatment and recovery can only happen if you are still around to receive it. My first wife is now living some distance away from me and quite happily I might add. Through effective treatment for both my alcohol and abuse problems, our lives are immeasurably improved and I no longer feel the need to control everyone and everything around me.
