Sister In Law Attempting to Sabotage Marriage

[kms1281]

After going to counseling myself to try to handle my SIL’s manipulation, , I have come to believe she has BPD. She has been spreading exaggerated stories/lies about me. She has told my kids I am mean to her. She has cornered my husband (her brother) and said I am a *itch and my kids wish I were dead and she was their mom. I feel like it’s best to cut off this relationship, but I am feeling extremely guilty about that. I don’t want to hurt anyone, but I cannot handle the constant lies and manipulation. The whole family sees it but refuses to acknowledge it. I don’t want to constantly be looking over my shoulder and now that the kids are involved, I am struggling to find a good solution that everyone is happy with. Suggestions?

Our objective is to better understand the struggles our child faces and to learn the skills to improve our relationship and provide a supportive environment and also improve on our own emotional responses, attitudes and effectiveness as a family leaders
