Sentence: I don't care?

I ask my cuisine if she wants to do something or if she wants to watch something on Netflix or YouTube. But she keeps telling me, "I don't care." what does that mean. Doesn't she really care, should I leave her alone? LG

She does not care.

Maybe she's annoyed with you or she really doesn't care what you two are looking at. Just watch any series and if it watches well and if not then it doesn't matter, watch it alone. That's family; you hate and love each other.
