I think Rotzilla has broken down your last post very well, don't really have much to add in terms of analysis. I think you are holding up extremely well through all of this.
I do think Rotzilla might have some really good points. I think the division of hh duties is a good "status check" for both you and her, let her think a little about her cake binge right now. She might also feel like she needs to distance with the comments and stuff.
I know it is tough to hear and tough to believe. Especially with the mixed signals and you can "see inside" her that she really does still care for you. I know it is tough to feel so close, yet so far away. Play the game the best you know how, don't let your emotions drive the bus. LOL I wish I could always apply this myself.
