Is it normal for a girlfriend to just react with "that's good" and nothing else

After you tell her that you had to call the crisis line last night and it kinda helped(while she was sleeping with her phone completely on silent)?

And nothing else? There's some emotional dissonance there that I can't get over and cant seem to figure out how to bring up with her. Similar stuff has happened before. She's autistic but I've told her I need her to show more empathy and given her examples on how. But she just says this stuff and when I tell her I'm hurt by something she's said (admittedly I haven't had the best reactions sometimes) she just says she can't be perfect.
