<human>: We've lived together over the past year. I believe at this point our relationship is really off the deep end. I think I need to get out. I'm unsure of how to break this to her. 
         I'm 100% sure she would take this very badly. I worry about self harm (She has a history of such). I also worry what she would do with out me. I pay all the bills, clean, cook. I don't want her to suffer, but I just can't suffer any more like this. 
        I love her, but our relationship is not healthy. I'm at my wits end, and it's starting to affect my everyday life. I don't really have any friends to talk to about this. Thanks =(.

<bot>: I think I need to break up with my GF, but I don't actually want to hurt her or for her to hurt herself.
