OK, so it is good that you set a boundary on accepting what you feel is emotional abuse. People can tell us a lot of potentially hurtful things, yet if we do not internalize it, we don't feel as though we are being abused.

The boundary is about protecting yourself, your emotions, until or unless you can not take what she says or does to you, personally. You needn't ever, yet it is always an option and possibility.

Saying "I will not accept this" (or similar) and then removing yourself from that situation is very appropriate, at this time.

Again, as far as waiting for a response from her, it still would likely be best that you leave that topic alone. When or if it happens, it will happen.

Why do you need a response from her? What is the reason for your anxiety over no response?
