<human>: Can you give me the gist of the text in a nutshell?

So, this is the first time in my life that I have actually wanted an Ex back. I am unsure of how exactly not to mess up and to actually get her back.

A bit of backstory, last january I met a girl and shortly afterwards we hooked up. I expressed doubt in dating, not because I didn't like her, but rather because I might have been moving a few hours away within a month. She persuaded me to stay and I got a job so that I could stay and date her.

Recently she broke up with me, quoting reasons like "i don't have enough time with College and band" and how she thought that i should be a nicer person (not to her because I was nice to her, but in general.) She has told me that she does love me, and is unsure whether she would like to get back together or not; but that she would give me a chance to improve my social interactions. In the past two weeks I have done everything in my power to be much nicer (mainly because my being a dick is a reflex and a habit from abuse.) So while i am still working on getting this to be second nature rather than having to think about it, I would like to know exactly how to proceed so that I can hopefully get back together with her.
<bot>: I was a dick so my girlfriend broke up with me, I am now attempting to be much nicer and would like to know how to get her back, or at least how not to screw up.
