Basically I thought she was better at being honest in discussions. She couldn't say "I understand your frustrations" or "I thought what I said was useful, but maybe you're right that it's indeed very one-sided" even once? That's on her. Even if I did go on and on a bit too much, I did actually give her (partial) credit for what she said.
Why do I feel bad about this, when she's the one not able to admit a single mistake.
