I wouldn't NOT respond to her -- that's just rude.
Are you READY to talk to her? Do you know what you want, what your boundaries would be this time? What would be different?
If you're ready, then meet with her -- but at a time that's convenient for YOU, not her first-offered day/time.
If you're NOT ready, then tell her something like "I'm not ready to discuss this yet; I have some decisions to make. I'll be back in touch later today or tomorrow."
