No, it is not common for people with Borderline Personality Disorder (BPD) to trust others too much. In fact, individuals with BPD often struggle with issues related to trust and interpersonal relationships. Trust can be a significant challenge for people with BPD due to their intense fear of abandonment and their sensitivity to perceived rejection or betrayal.
People with BPD may oscillate between idealizing and devaluing others, which can lead to a pattern of unstable relationships. They might have difficulty establishing and maintaining boundaries, which can result in unhealthy, codependent, or enmeshed relationships. This fluctuation in trust and emotions can make it challenging for them to maintain stable and healthy connections with others.
Individuals with BPD might also experience a phenomenon called "splitting," where they view others as either all good or all bad, without much room for nuance. This black-and-white thinking can further complicate trust issues and contribute to turbulent relationships.
It's important to remember that individuals with BPD can have unique experiences, and not everyone with the disorder will exhibit the same behavior or symptoms. Treatment, such as dialectical behavior therapy (DBT), can be effective in helping individuals with BPD develop more stable relationships and healthier ways of relating to others. If you or someone you know is struggling with BPD or any mental health issues, seeking professional help from a qualified mental health provider is recommended.
