What Would You Do?

You interview the mother separately the same day and she says she doesn’t believe the allegations and the boys are jealous she has a man. You ask the mother if she knows that her BF is a registered sex offender of a 1 year old girl 10 years ago (The BF is now 40 years old). She says yes but that was when he was 30 and it was with this “16 year old slut girl and he wouldn’t do this to my boys because he is not Gay because he has sex with me daily”. How do you respond and how do you ensure the children remain safe?
