Yeah, that's crap. A sarcastic sorry is crap, too. But, keep at it. Keep calling her on it. She has been doing this for a long time and needs to know that you don't like it each and every time.
My first thought is that you could have talked more about it, but maybe it is a good first babystep to just mention it. I was thinking how you could have asked why she didn't. Get the real reason out there and talk about it. Her reason is probably she didn't think about it. That's where you can say, "I really would like it if you thought more about me and what would make me happy sometimes. Asking you to think about me makes me feel crappy, but you need to know that I feel like I'm not getting "anything"."
