Hi, posting here instead of anywhere else as I'd like a feminist approach to this.
Dd has just turned 12 and has asked a boy out at school. Cue lots of lies about who asked out who, who they were hanging round with, sneaking her phone to text him late at night, looking at porn, disrespectful chat about their parents, he was disrespectful about his ex (an ex at 12 already!), and it was generally not very reassuring conversation. Dd came across as very needy, he said in response to her asking that he hadn't liked her so wouldn't have asked her out himself but figured seeing as she did that she'd be ok as a girlfriend 
I'm told he's a lovely boy but after experiencing abusive relationships myself, particularly with DDs dad, then I'm overly cautious and alert to any misogynistic and potentially abusive behaviour.
I know they are only 12 but she's portrayed herself as totally at his bidding. I've just found a note on her bed to him (in plain sight) where she urges him to dump her as she's a loser who almost got him grounded because both me and his mum have read their messages and are not impressed at all, nor with the lies and the porn. She then urges him to let her know if he still likes her and to hug her if he cares but says they shouldn't see each other. She's all over the place and obviously too emotionally immature to deal with a relationship.
She is grounded and had her phone use restricted due to the things she's been doing and saying and we have had several chats about respect, how women are treated in the world, self respect and boundaries but I feel I'm failing. Her dad is not on board at all and let's her do whatever she wants.
How the hell do I navigate this? She's becoming a strong minded feminist thanks to mumsnet I making me one therefore I thought a feminist approach might work best.
I've not met this boy yet due to her being grounded but had said he can come round once she's no longer grounded. I'm not too sure now though after reading how he referred to his mum and ex.
12 ffs!
