If this issue was raised before the camping, I would not have let them go.
Drama hurts kids much more than we realise, such as the campground incident ....and now, he's asking for them tomorrow?
This all became messy way too quickly. If your children were with a male friend of the family and were exposed to those pics, you would have gone straight to the police. Hell, I'd be wanting to kill the person.
This is sexual abuse. Let's be clear.
If it were me, there would be no way I'd be letting those children back with him. His incident afterwards....who cares. I would be strapping my children to my body before I'd let them go back to him.
I remember reading when my children were younger, that it takes but a moment for a child to be sexually abused (the robe incident above demonstrates that). This is not accidental. I refuse to believe that.
