A long time friend of mine is going through some rough times. He broke up with his long time gf, he proposed she said no and broke up with him, anyways he is having a really bad time with it, I noticed a few weeks ago scratches on both his arms. He gave me some excuse and I thought nothing of it. Yesterday I noticed the same scratches on both arms and look pretty deep. It’s obvious they are from a knife, he’s 28 years old really cool good job and all, so it’s hard to believe he’d do something like that. I’m not sure how I should bring it up to him.
