According to other comments, the paper he looked at was a job application form. So I guess he wasn't accepted into the job he wanted and was disappointed with himself. The story isn't clear but maybe that job was a ticket to a better life and he was turned down. He didn't want to drag his girlfriend into his mess, so he broke up with her. He probably hoped that she'll find a better life. He did find another job as a bear but I'm 100% sure if he's consistent he wouldn't want to let his ex see him in that state, especially since he still loves her so much. There! :D It's just my interpretation though.
