Your advice?

Okay, so I've been friends with this guy for four years. He's been bullied pretty much all of his life, and I've always stuck por his side. Even when people made fun of me for hanging out with him, I didn't care. We've always had this deep connection, and we loved each other like brother and sister.

Recently, these girls have been harassing him. Telling him to kill himself and saying he did things in which he didn't. I helped him through this rough patch, and it was emotional for both of us.

About two days after this happened, he slowly stopped responding to my texts. And then, he stopped responding overall. I thought he was just busy, but it turned out he was texting everyone but me. My friends would ask him about me, and when they did he just would ignore the pregunta and/or not respond.

A día o two later, I was on the bus, and he sat with another kid. The kid asked him about me, and the guy looked straight at me and dicho "we've never talked before." It honestly crushed me, and now I can't stand to hear his voice o see him around.

Why do tu think he did this? We haven't talked ever since, and I don't feel like he wants to make it up at all I (niether do I, really). Any consejos from the fanpop community?
