If looking at Susan as a possible DV victim and a possible victim of the worst type of DV, we see well-established and documented patterns. IMO and experience, these patterns of behavior between men and women transcend religion, economic accomplishment or lack thereof, race, location, time, and more. These patterns often include, for some reason, the victim moving away from the family. It is astoundingly common to see the victim losing control of the vehicle, money, phone, computer, home, etc. There is a natural progression. Many victims are not allowed to go to church or work at some point. What always got me was, these controllers do not know each other, or have a secret network, but they do the same things, case after case. This is why I lean towards Dear Susan getting in a confrontation with her spouse and this being the cause of her disappearance. Her case is classic IMO. I pray she will be found soon.
