How are you hoping that he will react to that? I ask because I have a tendency to want to tell people that I am a self-injurer, and I have learned that for me it is part of an unhealthy pattern. One reason some people (me anyway) SI is to get help, or to get someone to care. And that isn't really entirely unhealthy if you ask for help from someone who appropriately can and should help you, like an adult relative, a counselor, etc. But peers do not have responsibility or the resources to give that kind of help. Also, it sets up a dynamic in the relationship that is unequal - they get to be the strong one and you get to be needy and dependent. Ask yourself if that is the kind of relationship that you want with this guy.

I'm not saying you should never tell. Once you are in a close relationship with healthy dynamics, or if they start asking questions and you feel like you can trust them to be supportive, when the relationship has a strong foundation that isn't going to change too much by telling them about cutting, then it might be appropriate, or not - it is your choice. I have found that people will be concerned and supportive at first, but after a while they are tired of trying to help someone who is bent on self-destruction.
