Suggest Ways To Break Off Relationship With A Partner Who Is Emotionally Involved

Over the last couple of weeks me and my girlfriend have been become distant, whilst I am not as emotionally attached to her any more, sadly (in an un-arrogant way) she is hopelessly in love with me. I tried to end it recently, but I discovered she has been self harming. so I ended up getting back together with her, as I fear what she will do should we break up for good. I know that right now she has exams going on, as well as that her neighbour recently died so she is going through a lot of stress. But I feel unnecessarily going on with this dead relationship will only make things worse. does anyone have any advice with what I should do with her condition, should I tell her parents, her friends etc? another thing to mention is that when I confronted her about it, she swore never to do it again, but it must also be noted that this isn t the first time she has self harmed, she said that she did it around a year ago as well. And at this moment in time I am the only one to know.
