My 11yr old son got his heart broke for the first time, he’s taking it rather rough and I’m not sure how to help.

Just like the title says, my son was dismissed by his crush.We noticed last week his attitude changed and he was being more crabby. We just chalked it up to preteen hormones or whatever. His mother then noticed some scratches on his hands. She asked him about them to which he said something about a cat. Today we found more scratches and he’s confessed to self-harm. He said he used a pencil.. but we don’t really have regular pencils laying, and I’ve never really seen him with one—not that it’s impossible. The “cuts” or scrapes are all the same width and similar lengths but all straight.Well I looked through his phone, I probably shouldn’t have, but he’s only had one since Christmas. I’ve never invaded his privacy like this but I’m glad I did. This girl he has been talking to has been belittling him while he begs for her love. She sends him messages saying how ugly he is and his friend is hotter. She calls him trash and telling him he’s unimportant. It’s heartbreaking. He definitely isn’t taking the hint, worst of all.I haven’t approached this with him or his mother because it’s a really weird situation. I definitely want him to know he is loved, and this girl is just a mean little bitch—in good words though. But I also want to show him the side that accepts rejection with dignity. I’m not sure how to do any of that, and am Hoping you people can help! Thanks and if This the wrong platform to discuss this, im sorry. Also, I’m on mobile, so sorry I suck at typing. via /r/Parenting https://ift.tt/2wZvVuK
