Summer,
I'm not arguing with you about your ex. You may be right, I don't know him. I'm not saying he doesn't have personality disorders. I'm saying you are being way too broad in your generalizations.
Your "five percent" statistic is incorrect, IMO, and I also think there are at least as many people with personality disorders who AREN'T alcoholics/addicts as those who are. IOW, I don't think personality disorders and addiction go hand-in-hand. They certainly CAN occur in the same people, but one really doesn't have much to do with the other, except when they do occur together, one condition exacerbates the other.
