Your Partner And Your Sibling With Borderline Personality Disorder
He’ll suggest treatment
Your partner will reach the same point you and the rest of your family did years ago. He’ll think if he can just help your sibling—fix her—then everyone can have a nice time. So he’ll start researching therapists and support groups and medications. Sadly, he’ll find that she tried all of those already. You were all present for it. It didn’t work. He has to embrace that, like you all, he’s a bit helpless in the situation.
