Dumped and sleeps with her ex's friends?

I just got the weirdest overly specific craving I've ever had: I want an recently dumped FMC who decides to take revenge on her ex by sleeping with his best friends.

Bonus points if the ex was kinda abusive and the friends didn't know, and as they discover this throughout the story they are P I S S E D

I mostly read paranormal but I'm open for anything. I'm fine with M/M but I'm sensitive to bully romance.
