I think in my W's case, she is simply trying to spare my feelings. In fact, she said exactly that when I made the mistake of asking where she was going on Sunday.
She said, "I don't want to tell you because if you knew, you'd say that it's something you would have wanted to do [with me]"
I told her, "Try me".
After she told me, I said, "See. I am OK with that because I have come to accept the current situation and I promised you that I'd give you time and space."
This morning, I didn't ask her about her day on Sunday. Instead, she volunteered information to me.
She said, "It turned out that we got there too late so we missed the event. We're probably going to reschedule it to another day."
