I think this is the beginning of you moving on, which I think is a good thing overall. She told you she's not coming home back in July, those were her "cards" that you were asking for previously, maybe you just didn't want to believe it. I'm still going to stick to my original thought that there is someone else or was someone else and she's just in transition right now, looking for the next one.
As for you, a little cake eating sometimes becomes part of the equation of moving on, but it's part of the overall transformation, - go with it, have fun, no worries.
She has communicated she doesn't want to be with you, she's moved out, said she's not coming back, didn't want to work on a marriage with you, doesn't want a life with you, etc. those were all her decisions, time for you to decide what YOU want to do with your life.
