pp Narcissists almost never apologize for anything they do. It's always someone else's fault. The only apology you'll ever hear is. .. "I'm sorry BUT. .." The 'I'm sorry but' is not an apology but a blame - shifter. When someone knows damn well they owe you an apology they become obsessed with discrediting you.
"Too often we don't realize what we have until it's gone. Too often we're too stubborn to say, 'Sorry, I was wrong.' Too often it seems we hurt the ones closest to our hearts, and we let the most foolish things tear us apart." Unknown
