In my mind, we get Cathy whining from the beginning and Jamie being excited about their relationship, which made me immediately biased in favor of Jamie. In the end, if it's anyone's fault, I think it's Jamie's. However, their whole relationship is one that was doomed from the beginning (or end, if you will), so I think it's really just a case of two people who shouldn't be together fighting against that reality and losing.
