If he likes you that much he will STAY with you and Help you to overcome the challange of not cutting. He may beable to be a crutch, and help you to overcome it. And of course if He does not understand then he has a few choices. But if he Loves you that much, he will stay and help. It will help your relationship.

As far as a Therpist it is a good Idea, but I know it takes time for you to want the help from a professional. It will be hard to get the help, and you ultimately have to come to terms with SI in order sto stop.

Reaching out for help here is the place to start, and eventually you can get professional help. When you are ready. If you are not ready, it's really hard to get help.

and by the way puzzles are a wonderful distraction, use them to stop cutting, it will help!!
