D - interesting responses from your W! You're right, it does seem like she doesn't want to admit to any kind of feelings, yet actions speak louder than words! Give her time and space and see how this progresses. You are already doing a great job of it!
My H is a bit the same way. He brought me some flowers the day before V-day and I was in such shock that unfortunately the first words out of my mouth were "what are these for?" His response? "I don't know." I did go on to thank him, etc. but it was kinda funny.
Keep up what you are doing. Any news on the job front?
