No, I am not currently friends with C. I haven't spoken to her, or made any contact whatsoever, since the engagement announcement.
Neither have her sister, B or her brother, A. Which is one of the many reasons that I plan to stay friends with them.
Their DM has tried to contact C since the police intervened last week, in part I think to understand why. When the announcement was first made their DM wasn't sure what she was going to do. She says that she wrote C a card to tell her that she still loves her but that C & F's actions are indefensible. Their DM is horrified, angry and frightened.
Since the police incident last Wednesday their DM has contacted the local health services to explain that she believes C may be suicidal.
The services have taken this seriously. We believe that they have checked on C at least once.
To answer some other points made.
I am livid, as is my DH and B and her DH and A.
We are not entirely sure about C's movements since Thursday morning, we do know she hasn't been to work.
We have no reason to think that F has been back to C's house and the area since Wednesday evening. His car is still parked outside he hasn't moved it since Wednesday.
F does earn a good salary. Our guess is that he would be unlikely to be able to buy a car, pay rent and organise a place to stay and buy everything from clothing to toiletries to kitchen utensils immediately. Which leads us to believe that he is still in custody of some type.
C has two employers the family have informed C's NHS hospital employer that she is engaged to a paedophile, has put DCs at risk and that they should contact the police for further information.
The second employer was more difficult as she owns a partial share of it. In the end her family spoke to another senior owner and practitioner.
Thank you for the tip @SuperCaliFragalistic I have passed this on to the family in order for them to contact probation services. We know in his case that he manipulated images. The police couldn't find any evidence that he had put his hands on DCs.
She hasn't babysat any DCs that we know of and she doesn't have many friends.
Without going into detail we think that F is able to manipulate his employment so it wouldn't matter if anyone told his employer, he will go on to the next one.
None of us, including her DM, will forgive C.
Yes @Justilou1 the police did jump fast. This weekend the people from the original gathering congregated without my DParents or C and F. We talked about all of it together. One of us did say they think when the detective told us that he is highly dangerous it was because she knew that he has been reoffending or escalating.
I will keep posting when we know more.
