On the subject of the ring.. I'm wondering if her ring being cleaned was just an excuse for her not wearing it for ages while she continued to be in denial about things falling apart? Maybe Joe wanted to call things off or slow things down but she was in denial and kept thinking he'd change his mind etc. Or something happened so she took it off, didn't wear it for ages but they continued to put on a show until things properly ended. Just seems weird it was 'being cleaned' before all this.
