Maybe you can just ask her that.

And if she's only mentioned it 2-3 times and each time was in the support of the argument that she does care for you, evaluate that and see what seems more reasonable to you as far as her feelings- she secretly (?) resents you, or she might just really want you to get that she cares, or perhaps some of both. What does your gut say? Not your fears, but your intuition.

Or perhaps it is not that she resents funding the therapy, but maybe regrets that you didn't learn from it that she cares for you?
