I am not convinced. I think the fact that she couldn't terminate with you when she knew she should have done, and only eventually terminated because her hand was forced points more to the fact that she did care about you rather than she didn't. She didn't want to have to terminate you. She knew you needed the support and she cared too much to end the sessions when she should have. The abruptness of the termination is because she wasn't given a choice about it.
Yeah she did the wrong thing and should have terminated your sessions earlier and not lead you to believe you could carry on. But none of that was because she didn't care. That's your own stuff kicking in there.
