Right and she decided because she cares.

What she is doing now... is setting the boundaries around "the deal."

The session frequency is confusing, but I don't think the blah blah blah about the $$ is unusual, especially if a T has been "scammed."

She wants you to be aware that this is a temporary solution should you agree.
If your budget increases and you can pay $10 more, you should. This is not "for the next 5 years, you will pay only "x""....

Remember this is her job.... she is re-establishing a contract with you.

You don't know her financial situation. She might really only have "x" spots for reduced fees, so she has to make sure that they are used honestly.
I was trying to find the article on the number of people who do not tell their Ts that their situations change, but I can't find it now.

But she cares... because she offered.
