Your Partner And Your Sibling With Borderline Personality Disorder
She may try to tarnish your reputation
It’s hard to explain to your partner that, there may come a point when your sibling may go to him and tell him terrible things about you that are not true. Or, at the very least, don’t tell the whole story. If she’s having an episode, she might turn on you and, as a result, try to turn your partner against you. You have to prepare your partner for this.
