False accusations

[NTWMever]

Good morning,
My 35yo adopted daughter’s symptoms have never been this bad.  She has been declining for months and she now has done the worst thing again! I am divorced and  my grandson (her nephew) lives with me.  My daughter with BPD  has reported her father to the children and family services.  She has said that she does not think I am keeping him safe- and that her is accusing her father of sexually abusing our grandson.  This is the second time she has done this.  I do not believe it for one second.  Last time or this time.  She is dangerous, in my opinion.  She can say anything about anyone!  My ex-husband will be devastated if he finds out it is her who made these accusations.  She also now blames me for ‘allowing this to happen’.  That is the worst event of many over the past 8-10 months…
The hard part, too, is that my grandson adores her!  He always wants to see her and call her.  I’m always making excuses that she is working etc… Christmas will be a blow when our traditions will not include his aunty….

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
