Honestly I get you, I hate the world GenAI is making... but you can't control what your partner does. You've told her your stance on AI, and that you don't like how dependent she is on it - but it's her decision and responsibility as to whether she acts on what you've said. If her rampant AI use is a deal-breaker to you, then act on that. Otherwise, if she refuses to stop - then it'll have to be something to disagree on. Draw the line on things you do together.
