What do I do?

I told this girl that I was maybe interested in buying makeup from her, I told her 3 days ago. She sales younique. I told her what all I was interested in buying, keep in mind I told her maybe. I wasn’t sure if I wanted to buy or not. Well she just texted me and told me she ordered all the stuff that I wanted. And I didn’t even tell her I was buying anything yet! I wanted to wait and see how much bills would be first. Because that makeup is pretty expensive. What do I need to tell her or say? She ordered all this stuff without even getting a for sure answer out of me. Do you guys think she went ahead and ordered it just so I would have to buy it or what?
