My daughter is 15 she has not been formally diagnosed with BPD but has literally every symptom which have started displaying themselves over the course of the last few years (her older sister my 27year old does have a diagnosis). She lives with me, her step-father (he has raised her since age 6) and her two younger brothers. Her bio-father is an alcoholic and drug addict who is in and out of her life (we got her a phone last year and she has been communicating with him; but he is very sporadic with when she speaks to him).
About three years ago she accused my husband of being inappropriate with her. With much digging it was determined he was hugging/kissing her and she felt it was sexual abuse. He stopped hugging her or anything; we didn't hear another word and she started coming back to him for hugs & kisses. In July her grandmother (Step-dads mother) passed suddenly and it caused a lot of stress in the house. Suddenly at the beginning of this month she accused my husband again of sexual conduct - this time it was a step-up (touching her under her clothes - no penetration and making her touch him over his pants). She said this has been happening for four years!! She reported us to CPS and has been removed from my home. My husband has retained an attorney as he could be facing 60 years in prison (he is 67 so the rest of his life). I don't believe the accusations - the social worker assigned makes me feel like dirt for that but she was close with him, never alone with him, and my husband loved her like a daughter.
Additionally as I stated my 27 year old does have BPD and a number of other diagnosis. She was sexually abused as a child by a friends father and has accused a number of people herself (including the 15 year old's bio-dad thought never formally) She is in CONSTANT contact with her sister. Recently the 27 year old discovered she and her husband are about to be homeless. As neither has a job they will have no where to go. She came to my house trying to convince me to get rid of my husband so they can move in with me. During that conversation my 15 year old went upstairs - the 27 year old followed - when they came back I was told about these allegations. The 27 year old claims her sister has been saying this to her for years. When I told her I did not believe it and felt she was putting ideas into her sisters head she told me I was a horrible mother and she doesn't want anything to do with me.
Even worse DFS is placing the 15 year old with her dads family (when he was told about the allegations he called me drunk and threatened my life) and is giving me supervised visits with the 27 year old supervising (I am going to fight that in court). My life feels like it is spinning out of control and I have no idea what to do. I truly believe my 15 year old really believes this has happened and believes I am taking his side! She is setting herself up for disaster; she calls the initial investigation DFS worker her best friend and won't do well when she leaves the case, is ending up with her dad's dysfunctional family, is to deeply involved with her sister, and there is nothing I can do. I have been pushed out by this case and her accusations.
I am sorry for the long post I am just scared for everyone involved and don't know what to do next.

As a self-professed "feminist" who vehemently opposes victim shaming - my 16yo daughter has absolutely put me through the ringer with similar behavior. She's been sexually active for two years now, and after each relationship, she will inevitably accuse the other person of raping her. She also accused the neighbor-kid of touching her inappropriately. Then she'll say she misunderstood or misread the situation, and it WASN'T rape. But by then she's already accused the person and school officials (and in one situation, the police) and other parents are involved.

I'm scared to death that she is going to be raped and I am going to doubt her. The thought breaks my heart.
