This is a classic case of miscommunication: there's evident misunderstandings on both sides, and that's totally normal, since no human is a perfect communicator. My advice (as somebody who's been in your shoes), since this is the only occurrence of this behavior so far, is to reach for mercy instead of justice and try to obtain her point of view through direct, good-faith conversation. Even if you disagree with her priors or decisions, you'll learn something valuable. Emphasize that you don't hold anything against them but just want to learn from the situation, and no egos will be injured. People on the internet can spend all day pontificating on what she or you might have meant or felt, and what the greater ambitions of yourself or herself might be, but it's all futile because (1) it doesn't solve the problem for you (2) none of us know you or your manager. Instead of reading every comment on this thread, my advice is to schedule some time with her and air it out. Good luck!
