<human>: We've been dating for six months, but the last month has been near constant fighting, so I decided that I would break up with her today. I've been a really important part of her making it through her first year of college, so she begged me not to leave and said she'd change so I stayed, against my better judgement. She's had a history of cutting, and although she said she was done now she's cutting again. It's sounding pretty bad and I've come to the conclusion that we're drfinitely not gonna work out, so I feel like I should just end things now, but I'm afraid of what will happen if I do.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Tried to dump girlfriend, decided to stay, now she's cutting and I feel like the right thing to do is to break up for good but I feel trapped. Help?
