I REALLYYYYY NEED ADVICE!!!!!!

So my boyfriend has had a few serious exes before me... I am friends with one and yesterday his other ex messaged me saying he (my boyfriend) has a girls nudes who’s apparently 12... and then she sent me screenshots and on the screenshot it said at the bottom that he’d send his exes (Hillary) nudes to her if she sent the ‘12 years olds’ nudes to him so he did

So now Hillary’s nudes have managed to get to another boy and Hillary’s boyfriend wants to beat my boyfriend up

And at this point I’m not sure what to do!!!
