I think this song isn't about a particularly serious relationship, but rather something the character viewed as more of a fling. I understand the shed to be a brief sexual encounter. I think the souvenir in question is an actual book. The souvenir makes her eyes sore, not from crying, but perhaps in a more literal sense of looking at it too long, thinking about what happened. She loved the guy this song is about, not in a literal sense, but in a she was interested in him sense. After all it was only for his books, so it couldn't have been real love. She liked him because of his taste in books, but all she really wanted in the end was the brief sexual encounter. He must have thought there was more to it, and was heart broken when he realized it wasn't. The shame the character feels is from everyone hearing from that guy what she did to him, and her probably feeling somewhat guilty about it. She has "a reputation" now. By the song's end however, she's over it and doesn't care what the rest of the world thinks. She's ready to put the experience behind her and move on. She had sex with a guy she didn't really care about. So what.
