Of course, the breakdown in a primary relationship can be one of the major factors leading to homelessness. It is usually not the only factor though. One of the major stress factors is this kind of loss, of course, and is often associated with a breakdown of financial stability. And of most often of residential stability. Facing the trauma of a major breakup is very important, but regardless of facing or not facing it, it will bring with it trauma–anger, guilt, confusion, etc. A person may not even understand how the breakup occurred that may be the most disturbing part. You can tell someone it is not the end of the world, but that may not help at all, initially.
Have you experienced a major breakup and how did you deal with it?
