Boyfriend's Self-Harm Scars

Abbigal • ❤️❤️❤️
I've been dating my boyfriend Brenden for a little while now and on our third date, I looked over while he was driving and saw all these white scars covering the underside of his wrist and forearm. I'd never noticed them before because he has such dark arm hair. I don't know how to bring this up and if I even should! Please help!
