I have posted this in Lone Parents too.
My daughter has recently been reluctant to go to her Dad's due to his new girlfriend moving in. I finally persuaded her to go and she stayed over last night.
I picked her up this morning and she told me that she had spent the night sleeping in single bed with a 13yr old boy. Son of her Uncle's girlfriend whom she has met once before.
I have attempted to tell Ex that this isn't acceptable but he just says that I am nasty for thinking the worst of people.
I am at a loss. What can I do? I no longer trust him
