Cassie Did Not Lie When She Admitted "I Keep Making Mistakes And Not Learning From Them". She Broke Up

Cassie did not lie when she admitted "I keep making mistakes and not learning from them". She broke up with McKay by claiming she shouldn't be anyone's girlfriend because she doesn't think she's a good person. Her impulsive hook up with Nate was a self inflicted punishment. She has no self worth beyond how men see her as a romantic partner or sexual object. It doesn't justify lying to Maddy about it or being involved with Nate,but it simply comes from a low point that Cassie is occupying in her life. She is not a slut or homewrecker. She's simply a young girl who doesn't know how to love herself enough to avoid getting involved with toxic men.
