Alcohol addiction is a clear example of what I call a Love Buster because it causes so much suffering in marriage. Besides being physically and emotionally harmful to alcoholics themselves, addiction is also harmful to those whose lives touch them. Addiction makes people insensitive to the feelings of those who care most for them, and they will stop at nothing to feed their addiction. I am witness to many people whose lives have been ruined because they married alcoholics.
Alcoholics commonly engage in their most painful habits while under the influence.
Acts of infidelity are common. The fact that he or she is drunk at the time is no consolation to a grief-stricken spouse. Women often suffer cruel physical and emotional abuse from their alcoholic husbands. Even when he is not overtly abusive, he's often disgusting in the way he talks and behaves when he's drunk. Children of alcoholics, particularly girls, suffer greatly from the emotional turmoil of their childhood.
