Most Helpful Guy
I don't think it will make a difference if they are Christian or not. It is more about if the guy believes you are over your issues or not. No decent guy is going to be okay worrying about whether or not the woman he loves is going to start hurting herself.
You say you don't "really" do it anymore. That leads me to think that you are still hurting yourself at least some of the time. If that is not the case, then watch how you say that, or else guys might take it the wrong way.
