Justin Bieber is reportedly aching to get back together with Selena Gomez. According to Radar Online, Justin is texting Selena non-stop to win her back.  TMZ is reporting that Selena has blocked Justin from her cell phone.  A source said, "The problem in the first place is that Selena was a little bit of a jealous girlfriend and Justin wasn't really taking her feelings into regard. Justin doesn't see texting other girls as cheating, but he's promised Selena he'll stop if she takes him back. He is texting her like crazy trying to stay in her good graces. If either one of them slows down and they actually have the chance to spend time together again, they will end up back together."  The source goes on to explain that Selena has never been jealous of Justin's career.  Meanwhile, Justin is reportedly doing fine without Selena. According to Celebuzz, he is coping. Close friend and tour photographer, Michael Lerner, reportedly said, "Justin is doing fine just now, he is good. Justin is going to get through this. It's not the end of the world."
