Well, things became worse before they became better. DD didn't move as my DGS's Dad objected and threatened legal action so everything was put on hold however DD would not speak to me at all and we only managed to see our beloved boy when he was with his Dad which was better than nothing.
Things came to a head a couple of weeks before Christmas when the school raised concerns with DD and a SW became involved which upset DD so much that she asked BF to move out for a while ( DGS's Dad told me this). Also, worried sick, I had made an application under Clare's Law and the outcome came back just before Christmas- BF had a police record for Domestic Abuse and a Disclosure was made to DD . She did not tell him about the Disclosure but, thankfully, took it on board and ended the relationship. The day before Christmas Eve she came to the house and we talked for the first time in months. It quickly became clear that this man had been controlling and isolating DD for months. Some of the details were chilling and I have really struggled to understand how my kind, intelligent daughter could be manipulated the way she was. From what she wore to what she watched on TV, what she ate and who she spoke to were all controlled by him. One of my friends tells me that what has happened is almost identical to The Archers storyline .
Anyway, BF is away, DD and DGS are getting back to normal although both are receiving counselling and our family is slowly recovering but it has taken its toll.
I am so grateful for all the support I have received on GN( special thanks to those who suggested Clare's Law). That such a thing could happen to an ordinary family is terrifying.
