I want to tell you something from experience. Some young girls, despite what we see in the news, have no clear way to access their situation and level of danger. They don’t know how to stop what is happening.
When she told the first adult, one that could have advocated for her, what was happening and they did nothing, she was sucked further in.
They don’t have the reasoning, thought processes etc... The last thing you want to do is tell your parents.
Try to remember what being and thinking as a 12-14 yr old.
