If she takes notice of your actions, then maybe she would take BIGGER notice when you don't communicate at all? I know that sounds backwards, but that's how it's kinda working with my husband. He responds to me being there for him, asking how his day is, because I really didn't do that in our relationship.
The one day I don't communicate to him, he is instant to ask if everything is okay.
I would try it, just for a day to see what happens.
