<human>: Give me the gist of the text in a nutshell

So I've been dating this girl for about 2 months, and only been officially boyfriend and girlfriend for about a month. Lately she's been very short with me over texts and the last time we hung out she didn't act like she normally does when we were together. 

She just started school recently and just got a puppy plus she works everyday of the week for about 3-4 hours. I figured she was just really stressed and what not. Everything seemed to be going great until a few days ago when she started acting weird. Then she texts me one morning saying she can't handle a relationship right now and when I asked her to call me she said there was nothing to talk about. The last few texts she sent me were kind of rude. This all came out of nowhere and from the time I've known her she doesn't act like this. 

Is there something more to this breakup or is she really just too stressed and can't handle a relationship right now? I'm so confused and she won't talk to me about it.
<bot>: Girlfriend breaks up with me pretty randomly and now seems like she hates me. Wondering if there's more to this break up than her being too stressed or busy.
