If you've never been rejected by anyone, you're either Prince Harry or an introvert, somethings you just need to recast your net and try again. Just because you can't land your dream girl doesn't mean you have been bullied. If that were the case, Pardus would have killed all the sheeps a long time ago.
I'm agreeing with you, I'm not saying that him being turned down by someone he would have forgotten about in a month equates to him being bullied. But everything that has been reported so far points to him getting screwed around with. Is a lot of it him bringing it upon himself? Yeah probably. But that doesn't mean it didnt exist.
I fall into the school of thought of needing to just grow up and learn to deal with it, not everyone is going to like you in life. I was fucked around with in middleschool and the beginning of highschool but I didnt wind up doing a school shooting. I realized that words are just that, words, they hold no power over me. It helped that I got big because of football and wrestling but that's beside the point.
Besides too few people realize that any heartbreak because Stacy turned you down can be solved with some bath oils, Teddy Pendergrass, and Sleepless in Seattle.
