I found the information below on the web site of the Separated Parenting Access & Resource Center (http://www.deltabravo.net/custody/warning.php) Although the focus is potential problems with prospective spouses I believe that it pretty much refers to hpd issues.
• Warning sign: Does she become overly emotional about issues that don't seem to be that important?
Significance: Simply put, people who routinely engage in histrionics, extreme emotional displays, or who "create a scene" may not be stable. Be aware that this behavior is also present in some personality disorders.
• Warning sign: How many long-term friends does she have? ("Long-term" meaning five or more years of acquaintance)
Significance: An inability to maintain long-term friendships is a very bad sign. It's a reliable indicator that she is unable to maintain stable interpersonal relationships, a key foundation in any marriage. In short, if she doesn't have at least a few long-term friends, be suspicious.
• Warning sign: Does she have frequent conflicts with your friends and/or family? Have you stopped seeing certain people because of problems between them and your prospective spouse?
Significance: This is a classic sign of trouble to come, especially if you answered "yes" to the second question. Systematically alienating your friends and family through "manufactured" conflict is a classic sign of jealousy and insecurity.
• Warning sign: Does she have a history of seriously strained or conflicted relationships with her parents or siblings?
Significance: The presence of troubled or dysfunctional relationships with family members is an indication that she may have difficulty sustaining personal relationships. This is especially so if her conflict (for example, not speaking to certain family members) has gone on for an extended period of time.
• Warning sign: Is her personal and/or professional life characterized by frequent "crisis" situations?
Significance: An endless stream of crisis events is a sure sign that this person simply cannot "keep it together". It may also mean she has a need for this kind of constant "drama" in her life. Marrying this kind of person means that you will undoubtedly become part of her "support system". You'll also get to deal with her endless supply of "crisis" situations.
• Warning sign: Does her employment history include an abnormally large number of different jobs? Does she change jobs frequently, and if so, why?
Significance: Having a large number of jobs over time is another possible indicator of an unstable personality. Many times, the reason for the changes in employment will involve personality conflicts with co-workers, although this may not be disclosed to you (for obvious reasons).
• Warning sign: Does she have a history of starting things but rarely finishing any of them? (For example; schooling, personal projects or goals, etc)
Significance: This is another strong indication of a basic inability to commit to things, whether it be school, relationships, or a career. This kind of person is extremely dangerous to enter into marriage with. Often, the "reason" for quitting before the goal is reached will be a "crisis" situation, as mentioned earlier.
• Warning sign: Does she "fight fair", or does she resort to yelling, name-calling, door-slamming, leaving, or other similar behavior? Can she discuss touchy or uncomfortable issues without becoming upset?
Significance: Someone who can't discuss issues rationally is going to be a hard person to work on a marriage with. Problems will come up, and you need someone who will be able to work constructively on these issues with you.
• Warning sign: Does she use ultimatums to get her way?
Significance: Ultimatums are a sign that she cannot (or will not) or negotiate fairly for what she wants. This means that you'll have a difficult time reaching agreements with her on issues that come up. When someone uses ultimatums, what they're saying, in effect, is "I come first. What you think, feel, or want doesn't matter. I'm going to get what I want, even if I have to destroy our relationship to do it."
• Warning sign: Does she have credit problems or is she currently in debt? Has she been in debt often or continuously in the past?
Significance: A lack of credit-worthiness or a history of credit problems often indicates a low level of personal responsibility or accountability. It may also demonstrate an inability to fulfill their end of a contract....such as marriage.
• Warning sign: Is she unreasonably inhibited or prudish as regards sex or her sexuality?
Significance: Repressed sexuality often accompanies other, deeper psychological or personality problems. Repressed people are at much higher risk of having difficulties in other parts of their life, especially in interpersonal relationships.
• Warning sign: Has she ever withheld sex to punish you or to "get her way" about something?
Significance: This is childish and disturbing behavior in a relationship, and almost invariably gets worse after marriage. Be prepared to have this used against you with increasing frequency.
• Warning sign: Does she often harbor suspicions about her current friends and/or co-workers, and does she voice these suspicions?
Significance: These suspicions, which are usually groundless, will eventually turn towards you. This kind of behavior may stem from a Paranoid Personality Disorder.
• Warning sign: Does she try to structure your life so that she is the center of your existence?
Significance: Asking you to stop being involved in certain activities (typically activities she can't or won't participate in) is a way to isolate you and monopolize your time. She may also accomplish the same thing by "scheduling" every minute of your day, or by insisting that you participate in her activities to the exclusion of all of your pastimes.
• Warning sign: Is she used to "getting her way" by using her looks?
Significance: Some women who are used to getting by on looks may be emotionally shallow and insecure. They may also be unable to "pull their own weight" within the confines of a marriage. Be very careful, these women aren't used to working for what they have. They may in fact have an "entitlement" mentality.
• Warning sign: Does she pay an excessive amount of attention to makeup, clothing, or fashion?
Significance: Again, this may indicate an extreme shallowness of personality, if her concerns with superficial considerations like makeup and clothing are excessive.
• Warning sign: Does she often act impulsively, without thinking (or worrying) about the future or the consequences of her actions?
Significance: This is a bad sign, and one often goes hand-in-hand with credit problems. This one personality characteristic alone can be the cause of more trouble than you can imagine. People like this will do and/or say anything on the spur of the moment to get whatever it is they want at that moment, without regard to what happens next. Be very, very, careful.
