I would say She, this person, is not worth your time... It's clear that she doesn't care about what you say nor what you tell her... you could talk to her about it and have an understanding of why she's like this. But, at the same time I wouldn't waste my time on her and just go find someone new to talk to... Though, it's your choice to keep talking to her! I'm not saying you should take my word though it's probably best to talk to her about and if she doesn't really want to... then you can take the situation else where
