Before Xw left it was very crazy, she was crazy, I was going crazy. I was drunk all the time. When Xw was pregnant it was hell for her and for me. I started going to AA but she flat refused going to alanon. It was encouraged for the spouse to go to some AA meetings. I asked Xw and she agreed. Anonymity is the foundation and we live in a small community so we respected anonymity very much. I had a few friends that travelled with me. I told my than wife I will tell the other people you want to come, would they mind. I explained the respect involved in anonymity. One friend was very uncomfortable with my wife coming, He was sober a few months and in very bad shape, he wanted to drink really bad but wanted to stay sober more. The poor bugger needed a meeting in the worse way, he was terrified to go back drinking. I explained this to my than wife, would she mind sitting out this meeting, she took it right in the nose, I promised we would go to another meeting just her and I. A few days later my friend was good and was going to sit a meeting out so I asked wife and she was still bent out of shape at me for asking her to sit out that meeting. She said "NO, I was suppose to go the other day and you told me I couldn't go". Knowing nothing about emotional disorders at that point in my life I tried until I was blue in the face to explain the situation but she refused to listen to reason only that in her brain I told her she couldn't come to the meeting. She never did come to one and to present day, 10 years later my friend is still sober.

Everyone - not just pwPDs - is capable of suffering disordered thinking.
For example, many people who are in the latter stages of, or coming out of, disordered relationships are described as having temporarily contracted BPD traits.

pwPDs typically have more disordered traits, to a more pronounced degree per trait and for extensive or lifelong periods of time. They can also experience lucid states.
