"Selena broke up with Justin about a week ago. It's been a really challenging experience over the last year because of their crazy schedules," one insider tells Us. "Selena definitely had some major trust issues with Justin."
The pair have had their share of problems in the past, although a source close to Bieber cautions that the breakup, which happened on Halloween, might not actually mean the end of "Jelena."
"They are [young] ... it changes from day to day. Right now it is a break and tomorrow it could be back on knowing them ... it's hard to say how they will end up," the source says. "Maybe she feels more serious about it this time. We'll see."
"It's hard," she admitted of the Internet haters. "It hurts, it really does. I don't feel like I'm doing anything wrong. I've been best friends with him for a very long time. It does hurt my feelings a lot but I try not to focus on it. I have a strong family and great fans."
