Playing the tit for tat game (you taking down a photo and putting it on your nightstand just like she did) will get you nowhere and only fuel the cycle of negativity.
Does it really matter why she took the photo down? It doesn't really and I doubt she is going to say "OIN, I took the photo down because I enjoy being a total bitch to you" and I really doubt she is going to say "OIN, I took the photo down because I might not be living here much longer". All she is going to do is grunt so why bother asking?
The next time your W communicates through the dog why not just say "W, if you would like me to do something for you please ask me directly and not ask through the dog".
And while she may have been playing a game on the computer my point was she came home and gave attention to the dog then went upstairs to isolate herself while paying you no mind at all. She may have not been pouting in the actual sense but it *is* her form of a pouting ritual that you seem to respond to each and every time.
Like today when your W asked if there was more of what you were eating. Why not just say "yes, W, there are more <insert food item here>" and leave it at that. Instead you got yet another mumbled response when asking her if she wanted some.
I would start saying in a polite yet firm fashion "W, I am unable to decipher what grunts, moans and mumbles mean. Please use words when communicating with me". I mean c'mon, do you think she could grunt and mumble at work and not be told not speaking is not acceptable?
Your W doesn't seem ready to treat you or look at you like a H or even a friend but that doesn't give her a free pass to treat you like garbage.
If your W doesn't want to communicate with you sans dog or mumbles that is her choice but at least you put it out there that it doesn't work for you any longer.
