My friend, who I thought I was really close to, apparently had been dating this guy before she moved away. If it were just they got together a week or two before she left, it would have been fine. But no, they were together for much longer. So much so that this guy was saying he loved her and wanted to marry her.
It really hurt me to discover that me and her weren't as close as I thought. In fact, reflecting back on the time we spent together, I was always invited by a third party, not her. The only time we ever spoke to each other alone was on the bus ride to and from school (which made her whole relationship make me angrier, because she could easily have told me). To discover that I may not be her friend just sucks.
