I needed to read what you wrote above. You have described my situation/your A to a T.
My W keeps telling me that she's ended the "EA", but then I find out she hasn't. She's still affectionate to me, even though she asked me to leave the house/said she wanted a separation on Sunday.
I moved to my parents house on Sunday evening. I saw W last night, and she hugged me, then kissed me a couple times. I didn't want to completely pull away from her, but I definitely wasn't completely into it either.
It's good to hear your description of what you were feeling at the time, because it provides some insight into what I'm dealing with.
