Dealing with someone who never think they are wrong is absolutely draining . No accountability, no reflection, just excuses and finger pointing. everything somebody else fault, everything a misunderstanding, everything get flipped back on you. After a while you realize you not even arguing to fix nothing,you arguing with somebody who already decided they can’t be wrong.
I heard a therapist say, “Your feelings are always valid, your behavior is not.” She explained by saying feel what you feel BUT you need to be accountable for what you do as a result of those feelings.
