The way I see it is you love her unconditionally - a rare and beautiful thing. Her love for you was conditional - she depended on you for self love... when you went your seperate ways you no longer filled her need, thus the break up. She now has no-one to validate her self-worth, in that her current turmoil and pain. Can you talk with her of these things - I feel that by talking to you about hurting herself she is actually asking for help?
It has almost been a month since your post... are you able to update this thread to where it's all at? I am interested
