Repeating myself over a single issue feels like nagging to me....I have communicated this before and she knows it.
Yah, I get what you're saying. I've been there. Just try to give her the benefit of the doubt sometimes if you can. (of course, not to the extent that you end up feeling disrespected... don't want that for you)
I know you know that behavior change takes a long time and it's hard and can be scary. Sometimes it takes repeating what you need a few times. If she doesn't 'get it' right away, it doesn't mean she's not trying.
I cannot complain for not receiving from others, that which I've never asked them for.
