Why don't you call her up and find out if that's the issue? If she didn't think your price range was realistic or if she needs more pay or some similar issue she should have been straight forward about it and told you.
Either way I think calling her, figuring out a lesson plan, and being sure you are clear on whether or not your price range is reasonable, ect. is a fair plan. You can ask, without arguing, what she thinks about you going and seeing other horses, including rescues. You can suggest you see them once and if you think they fit then you schedule a time she can come out too to help you see any potential problems.
Just talk it out. Be very clear and be sure you get clear answers. Either you can figure everything out with a simple phone call and everybody's happy or you can realize it's just not going to happen, in which case you can move on.
