<human>: So me and this girl have been dating for almost two months now, and my heart was never really in it. She's nice and cute and all, but I just don't like her as more than a friend. She is crazy about me and I thought I'd give it a shot. I thought in time I might grow to think of her differently. I found, however, that the feelings I had were mostly physical.

See the thing is, she's a little emotional. About a month ago I told her that I wanted to take things slower and she started crying because she thought I was breaking up with her. Anyway, the past few days we haven't talked much; I've pretty much retreated from her. I texted her saying that we need to talk, and well, here's her response:

    Her: About?
    Me: Stuff
    Her: Okay, when and how?
    Me: Whenever you want and however you want
    Her: So now over the phone?
    Me: I'll have to charge it up first
    Her: Okayy.

Again, she's a nice girl, and I know she'll be devastated when I break up with her. She's been crazy about me for a couple of years and I'm ending it pretty early.

Finally with my question, is it rude to hang up on her if she starts crying? I wouldn't just end the call, but I'd be like "Again, I'm really sorry, I just don't feel that strongly towards you. Anyway, I'd better go"

Can you condense the text into a few key points?
<bot>: Breaking up with my girlfriend because I don't have strong feelings towards her, she's pretty emotional and have no idea how she will take this / how to not make it a 3 hour phone convo
