My 10 year old DD went to play at our friends house, they have two children, one of the children is a boy aged nine. They’re friends. My DD is a very innocent 10 struggles with anxiety and is extremely kind. They were in his bedroom and he asked to see inside her knickers, she didn’t want to show him but he said you’re a scarlet cat and a wimp and in her words “she finds it really hard to say no to people” so she did and he touched her and told her not to tell us what happened. When she came home she was in a terrible state and it took me ages to get her to tell me what happened. She kept saying I said “no and I didn’t want to but he said I had ti and you know I’m no good at saying no to people”. My DH has already gone mad at the mum, she’s questioned boy and obviously he’s denied it. We believe our daughter. The mum is minimising and saying they were both curious and perhaps playing and now our DD wishes she hadn’t.
Our DD said she didn’t want to, he said she had to and told her not to tell us.
Where do I go from here? Obviously that’s the end of any friendship but do I report it?
