I find going twice a week to generally be helpful for me, and it seems like she has a plan for it. *But* if she's pushing you into it, and you don't want to and/or you can't afford it (in which case you could maybe asked for rate), then I could see your reluctance. One thing you could do is try it out, see how it feels, and you can always switch to once a week. I do find her saying to buy her own book a bit sketchy...(makes me think of a couple professors in college who did that...)but maybe you can find a used copy or get one for a Kindle? (If you don't have a Kindle, you can also get an app for your computer or I think phone to read Kindle books.) My T has recommended books to me, and I've generally gotten them,but he hasn't said I *had* to buy them. I can see their value though, to give you background, and so maybe she wouldn't have to spend as much of your session time explaining things.
