Those who have a relationship with someone suffering from Borderline Personality Disorder (BPD), will know how difficult it can make every aspect of life.
Mental Health and Setting Boundaries with Family
Mark Diehl, the author of the memoir Stealing Cinderella: How I Became an International Fugitive for Love, has been there. His mother, who suffered from BPD, often harped on worries not grounded in reality. For example, she was paranoid that his daughter's ice skating lessons might bankrupt his family.

She was reminded of her inferior status constantly, including through her parents' coercive and punitive behavior."

Both Mark and Jennifer experienced incredibly difficult childhood circumstances.

Another complication of their relationship? Their interracial relationship brought about many difficulties, including angry stares and even threats to their lives. Taxis would ignore them, and restaurants refused to serve them. Even their employer forbade them to see one another.

Jennifer risked being attacked by total strangers because of her relationship with Mark. She was in fact, brutally beaten by her parents and locked in her r...
