I didn't fully feel like it was a breakup either - if it wasn't for Shawn saying goodbye after she had left, I wouldn't think that he did either, but I think that was just the pessimist in him. I think Angela truly believed that she would come back to him, & even if he didn't believe it (or couldn't, because he was scared to get his hopes up), he'd still get back with her in a heartbeat when she did come back
