Suspiciousness and a quick temper are typical of this emotional style. Often the mistrust stems from having been physically, sexually, or emotionally abused. People of this style tend to gravitate to relationships in which their worst fears are confirmed, getting involved with people who treat them badly.
If this describes you, you may want to work with a therapist specializing in clients who have been abused. Treatment may involve revisiting your memories and expressing your anger, which is an essential emotional step. Mindfulness can help you become aware of your tendency to assume betrayal, and help you challenge those thoughts.
