To speak to my friend about leaving her boyfriend?

[MidoriNoRingo]

Had a few drinks with an old friend the other night and the conversation moved onto sex. She’s been seeing a guy for 4 months and she said he likes her to dress up like a school girl. To me that’s a huge red flag when she has 2 actual school girls living in the house.
I asked her where she got the outfit from and she’s actually wearing the same uniform that her daughters wear to school. I’m so shocked and not sure if I’m over reacting here but that’s fucking gross isn’t it??

Absolutely fucking gross. I’d have to say something.

That creepy and concerning for her poor children she putting them at risk and ignoring this massive red flag to get her leg over

I agree that it’s gross / red flag worthy / top quality Ick.
She needs to get rid of him.
Has he got photos or videos of her?

Can she honestly not see anything wrong with that?!

They are both disgusting and I would be dropping her very quickly, and giving a heads up to the safeguarding team at school.

Even if she leaves him she still found it appropriate to basically dress up as her daughter and shag her boyfriend. Gross.

Grim, awful she can't see that.

Have you actually told her what you think OP? It doesn't sound like you said anything at the time, but you should definitely tell her. Could it be that she's been lost in the moment at the time, and it hasn't crossed her mind how risky this situation is for her girls?
