Petty

When you know that you're wrong but decide to take things in the opposite direction of conflict resolution because you chose to believe your false reality and obsession with your own perspective like the narcissist you are

"Wow Chelsea is being ridiculously petty....she knows that she's wrong but continues to push her agenda and put her relationship wtih Oleg at stake to fuel her own ego and somehow prove that her invalid perspective is the right one....I dont know how Oleg deals with this....poor him."
