Nothing can be solved that way

Literally nothing can be solved that way. Each puts the blame on the other. Each has inordinate ego defence. Each doesn't want to share in the resposibility. Each refuses to say " Sorry". Each looks at the other like an enemy. Each lack the self confidence. Each does not have a minimal degree of diplomacy. Each considers the other the problematic partner. Each is closing the door for any resolution. Each avoids looking in self mirror to see how he looks. Each loses the insight and does not care about any consequences. That usually ends by a total crash. She goes her way and he goes his and the beautiful story that meant to be forever ends so fast.
