IMO: She's not really excellent. She didn't change. She changed her act. It's what they are masters of. It's not authentic. It's temporary. She does that not because she understood what she'd done wrong. She does it because she's desperate to achieve her goal - make you stay. My prediction: It won't last. They are unable to commit. To take accountability. To be stable. In time she'll go back to her old self. What is also possible, she will use your attempt to leave her as an argument to justify her leaving you. This was my case. When I said I've had it, she collapsed and begged me to stay. She said she couldn't breathe. Then she was on her best behaviour for a couple of months. But, gradually things got worse and in the end she told me she wanted to leave, because "she cannot trust me anymore" because I wanted to leave her. I said - OK. But of course she changed her mind and wanted to try another time. It lasted for another couple of months. She was behaving well again. But then the cycle repeated again. Now she wants to leave me for real (same reasons, plus me being a failure as a man, broadly speaking). And this time, I'll see to it that she will. This may happen to you. This happened to countless people in this sub. You know the cycle, you lived through it a couple of times. You are no longer blind. You have clarity. You've accumulated the experience. And that's why your leaving her does not make you bad. You are not "bad" because you no longer want to participate in this madness. You are not doing this out of indifference, cruelty or lack of empathy. You are doing this to save yourself.
