You probably will think I am being but you haven't put up with her for 6 years.
SIL is 16 and has "ADHD" I put that im quotes as i everyone knows she plays on it!
She is violent towards he mum and family in fact the other day she went for her Step D and when he pushed her away she called SS on him and her mum, and this isn't the first time she has done this.
She has threatened me with SS In the past because apparently i wouldn't let her see DS as much as she'd like.
TBH I think she has a bit of an obsession with DS!
I always let her come over to see DS and take him over to MIL's as much as i can.
But she always kicks off because they rest of the family see DS more that her!
In the past she has done some pretty horrific stuff, she made up a lie about DH a few years ago when DH was about 14-15 that could of got him in to ALOT of trouble tbh i dont even want to repeat it, but you can probably guess.
Anyway yesterday she phones me up having a go because i didnt bring DS over to see her on her birthday.
I didnt even think she was at home as she was away the previous day and i had no idea when she would be back.
She then had the cheek of saying that DH got payed the other day so why didnt we get her anything for her birthday, yeah he got payed but we had £700 rent arrears to pay!
Anyway i just told her to leave me alone and hung up.
TBH I don't want some1 that is so handy with the SS's number and doesn't care about the implications afterwards in my life, not to mention the other things she has done.
AIBU to never want me or DS to have anything to do with her again.
Sorry for the long post, i didn't another one and it was better but I deleted it all before i posted it 
Thanks for reading
