That right there tells me she should have been more attentive. She knows about your situation and she should have made sure that she understood what the expectations were. That's why she gets the commission, because it's HER job, not yours. It sounds like she has been making you do more of the work than you should.
But I am happy to hear that you are all the same page now and she knows that you are upset. Hopefully that will solve everything and she'll be better. If not, c ya! Of course, there's a chance that she has also had some things going on her personal life that we aren't aware of, so good for you for giving her a chance to redeem herself tomorrow.
