If a guy really cares about you, he won't be scared off by your SI scars. If he runs, he wasn't worth your time anyway.

I started SI-ing before I got married, but didn't do it often, or very deep. It got really worse after we got married, and my husband was freaked out at first. But, I guess he got used to it. Now he doesn't say much anymore, he knows it makes me feel better. The cuts have gotten deeper, the scars have gotten worse and bigger, but he still stands by me. True love will overcome anything.
