I have name changed for this (username is from a dutch expression 'handen in het haar' which is a saying indicating I am at a loss as what to do). I am based in a Dutch-speaking country.
Yesterday I decided to check my DS's phone. He is 11 and knows I check his phone regularly.
I found a conversation with a girl, his girlfriend it seems, though I don't think they really talk on the playground. In the conversation they are discussing self harm, suicide and she says her dad doesn't treat her well, also sexually.
This morning whilst he was in the shower I saw he had a knife next to his bed. I took it away and into the bathroom just as he had finished showering and saw he has lots of cuts on his tummy.
I have just hugged him and said we will talk today.
Now I could really use some advice on what to do about his self-harming but also the girl. From the messages she seems really troubled. Do I contact the school, her mother?
Thank you!
