Phew - now all that bizarre stuff is coming to a natural end can I have some attention please? 
I don't want to drip feed so ask away if things aren't clear but there is a backstory that a lot of you are aware of so I won't repeat the whole thing now if okay.
DH got DSD's phone bill today (she is on a contract which is £20 a month for her iphone as he works for a phone provider so half price of £40) it came in at £60 and when he investigated it was because she has been sending picture messages which she has been warned about and spending too long online.
First question - what would you have done?
He called her up, told her what had happened and said he had disconnected her internet for one month (she can still use calls and texts) and she would have to pay him back.
She said she wasnt happy with that, not fair etc etc (standard teenage, no big deal)
But then she calls back and he was in the loo (he actually was not like piratesdh) so she left him the longest, eaariest VM I have ever heard. Totally cool calm voice, sounded just like her Mum, emphasis on same words etc. saying the most horrid, personal things ranging from "You are dead to me, I have never loved you" to "Your beard makes me feel sick" "No one has ever loved you, no one cares about you" "Stepdad is my real Dad, he actually has a heart" "you disgust me and you will never see me again" "you have a hunchback you pathetic little retard" (he has a slight bump in his spine and it's one of the things that his ex wife used to pick on)
She says she'snot coming to us tomorrow for my DD's birthday party (She should be here tonight but as often happens, something else came up)
I could go on.
Where do we go from here? My heart is breaking for him. He has been amazing throughout this whole thing. When she originally pulled away from contact after CSAgate he took a while to decide if the time he spent with her should be "Disney" to protect the scraps of her that he had left, or if he should continue to try to parent her. He decided the latter and I am so proud of him as it isn't easy.
But this is just unbearable. Because of the scenario her mum has created, DSD is unable to see these situations for what they are. I mean, this is soooo normal. I don't expect her to say, "Why, thank you Daddy, this discipline will enable me to grow in to a responsible young lady" I would expect a level of resistance - maybe even a screamed "I hate you!" I know I said that to my dad a few time (Sorry, Dad - I now know how that must have felt!) but she can only see it in the context of how she perceives DH to have treated her Mum when they spilt up, and what a victim her Mum and her are and, crucially, the competiton for her Mum to be top parent.
I advised him to contact Mum and ask for a meeting with the three of them to get all this out in the open (mum has signed that she's having teen troubles) but Mum as come back to say no, I have the normal teen roblems but I can handle them, DD just doesn't want to see you and hasn't for quite some time - I have told her she has to as it's the law (WTF!? It's not, and DSD isn't that stupid. Plus, what kind of a mixed message when back in December she was told she didn't have to come here anymore as Mum was main parent and it was up to DDand her if she saw Dad!)
I'm at a loss. What can we do? DH is so upset.
