If you think it makes you look weak and gives her the upper hand, then you are weak and it gives her the upper hand. Simple as that.
There's a great line from the movie 'Road House' with patrick swayze
When he was explaining to the other bouncers how they should conduct
themeselves on the job and be professionals...
"If somebody gets in your face and calls you a c0cksucker, I want you to be nice."
"OK."
"Ask him to walk, be nice. If he won't walk, walk him. But be nice.
If you can't walk him, one of the others will help you. And you'll both be nice.
I want you to remember that it's a job. It's nothing personal. "
"Uh-huh."
"Being called a c0cksucker isn't personal?"
"No. It's two nouns combined to elicit a prescribed response."
"What if somebody calls my mama a wh0re?"
"Is she?"

if you're wondering what that has to do with your question.. think about it. Who controls the frame? You or her?
Are you leading or reacting? How about you own the situation at hand instead of letting what she may say or think
influence what you need to do.
