I was talking to this chick and she said this to me, ''If you want to talk about something else or don't want to continue talking, I understand.'' Is she being serious or is this something else?

The context is we were talking about TV shows and she was asking me about a TV show I watch and I wasn't too interested in talking about it so I said ''What do I look like, IMDB?'' I think maybe I was too rude? I said it in a joking way and was smiling during. So Idk.

I'm not sure if shes literally ok with not talking to me or if she's being submissive and actually saying she can talk about other things if I tell her what we should talk about.

Idk. Am I overthinking it? I'm curious what others may think she means here.
