Hey T, This may or may not be helpful but women do tend to be more mood driven.
Also, I myself am indecisive and often just want my H to listen while I talk out loud. I make decisions by thinking out loud, he makes decisions internally and only speaking when a choice is made. He gets mad at me for changing my mind, I get mad that he won't just let me talk w/o knowing what I want before speaking.
One day I love my job, the next day I'm fed up with it. Same w/ the kids, one day they drive me nuts, the next I miss them while I'm at work. A lot of women just want to be able to come home, unload what happened in their day, and then start their night after being "heard." What your describing just sounds like she's looking for someone to listen to her.
I'm sure there is other WAW stuff mixed in, but mood driven actions/feelings might stick around even if things work themselves out between the two of you.
