<human>: Can you give me a shortened version of the text?

I had my boyfriend write his thoughts about my self harm issues below:

"I'm in a relationship with a girl who puts herself in danger when she becomes upset. For example, she has resorted to drug use, speeding and running red lights, cutting herself, and most recently attempting to stab herself before I wrestled the weapon out of her hands. Although these incidents don't happen every time she's upset, only a few times in the 3 years we've been together, it is still very troublesome. I have stayed with her hoping that my love would provide a stabilizing force capable of helping her cope with her feelings in a healthier way, but with the knife incident a few days ago, its clear that things are only getting worse. I committed to many things when I started this relationship with her, but being responsible for her livelihood makes me feel like more of a caretaker or a parent than it does a boyfriend. Other than putting herself at risk, my safety is also at risk, and I never thought physical safety was something I needed to worry about in a relationship. After the recent knife incident, my initial reaction was to break up with her. I did this so she knew this was unacceptable behavior in a relationship. If I stayed with her she would think she could continue to act in that manner."

^After this serious incident my boyfriend made it clear he can't be with me if I act like that. Which is understandable, but I'm torn because of course I don't want to act like that, but I feel like sometimes I have no control of myself when I do self harm. I don't know much about self harm issues, so I'm wondering if anyone has any advice on how to make sure this never happens again, for the sake of my relationship. Or is this boyfriend not suitable for me and my personal issues? Thoughts?
<bot>: My boyfriend says he can no longer handle my self harm issues anymore. How do I stop? Or should we go our separate ways?
