she sounds like one of my friends. When she's wrong, she shuts down and tries to flip it on you. It's easier to "just let it go" than face the actual confrontation. She knows she did wrong but would rather avoid the consequences (i.e. talking it out). Talking about it is too much for her insecureness.

This is happening with 2 of my friends now and I'm trying to avoid being caught in the middle even though I think one is more right than the other.
