Im not sure if this is the right place to post but it seemed appropriate. Im a first time poster (long time lurker) just looking for some advice. I just want to give you a bit of background information first to put you in the picture.
Found out beginning of this year that ExH father sexually assaulted a female member of ExH family. Shes a child and it happened in public, was reported by someone who witnessed it.
I found out as my two young children had to be questioned by social worker/police, as it turns out he has a history of abusing young girls and has once been convicted years ago.
Initial concerns over my daughter as she had been very reluctant to see her dad (they usually went to the grandparents house) and had some behavioural difficulties. Social worker said nothing was disclosed but that both my children had said they were scared of him. An incident of violence was reported by my daughter but it was quite muddled/confusing.
ExH mother decided to stick by this man- not the first time. She told ExH that she doesnt want to die alone. Ex H has cut them both off.
I wrote a strongly worded letter explaining that there would be no more contact with either of them. She knew what he had done in the past, did not say anything, my children had been babysat by him on numerous occasions- alone. She responded by saying she understood, and goodbye basically.
The victim of latest abuse is too scared to speak about it now and since it happened another female has come forward about past abuse from him. Its likely he will go to prison.
ExMIL has just sent my DD a birthday card, signed from them both, with a large cheque and a cheery message like nothing has happened. Obviously I dont want it but I dont know whether I should just send it back or include a note clarifying the no contact, and if so what to write? I dont want to be nasty but I really need her to understand that its not appropriate anymore.
This may seem petty in light of the whole situation but really I just want them completely out of our lives, for my childrens protection, and Im not sure how best to go about it.
