Borderline Personality Disorder can reshape romantic life not only for partners, but also for children and the broader family system. On this page, we connect relationship strain—like emotional exhaustion, fear of abandonment, and frequent anger—with comorbid patterns such as PTSD, depression, and substance use. You'll also see how these factors relate to attachment outcomes and recovery trajectories, plus how treatments like DBT, MBT, and couples therapy may help.
