My daughter in law has diagnosed BPD. She has been hospitalized twice since she has been married to my son these almost 10 years. I am into my 2nd year as a widow. My son and daughter in law have 3 children.
Throughout the years, she has told horrific stories about things my neighbors did to her and then said the horrors never really happened, plus many made up stories about me, my husband, her parents, her sister, and on and on. She is very intelligent and can suck people into her lies, other family members and friends. My son has phoned me and/or come to my home many times when he and the kids have to shut themselves behind locked doors to get away from her episodes or been able to leave to get to a safe place. It has been a long and hard 10 years on this family.
She has kept the grandchildren from us more times than I can count and usually for many months at a time. We are in that cycle now and I have been shunned from the family, again, but this time, I am alone without my husband. I see it when it is happening and she is starting to spin out and I knew this was coming and tried to keep my distance but it is never far enough when she has her mind set on causing drama and upheaval.
This last episode was so bizarre and nightmarish. I should have never stood up for myself, as it really caused the escalation of her spin. I know my son is trying to keep his family together and plays into her episodes to try to keep some peace at their home when it is my turn for his wife to turn on me. My son was in the other room working from home and she started saying things and acting like we were fighting and my son came out of his office and told me "to get out of his

#$%ing house" in front the of the 3 grands, over and over as I was trying to leave and the kids were trying to hug me (they must think this is normal by now?). I did not respond with yelling or cussing back, I was just trying to get out of the house before my son put hands on me because that is how the situation felt. It was like a nightmare. It is by far the worst situation I have had with my BP DIL and I know that the escalation and her thinking she can treat me this way stems from the fact I am now alone without my husband.
Please help me with some coping mechanisms.
Thank you
