Late to the game

Thank you all for your help so far.
I have read DR and all of the links and am actively using the info. My plan is to continue detaching in a friendly way. Also, trying to learn more about relationships, specifically mine and how we came to this point.
Until now, my version of detachment was just that. A complete detachment, as if she was not in the room. The complete opposite of begging and pleading. Zero pursuit. It needed to be this way for my own sanity at times.
While it calmed the emotional waves, it did nothing to being the best I can be around her. That's where I need to improve, regardless of any reaction from her.
To paint a better picture for everyone, it was at the point where there was no response from her to anything. Hello, goodbye, good morning, good night. All of them met with a blank stare at best. Her non response prompted me to go silent around her.
One other thing I should mention that is new since BD. Besides going to work, she rarely leaves the house. When she does, she goes into detail about where she is going and how long. Ex: "I'm going to xxxxx to pick up xxxxx and then I'm going to xxxxx to grab xxxxx. I'll be home in 45 minutes". She is home in 45 minutes with the items she said she was going for. I'm curious as to why she can't say good morning, but feels the need to tell me in detail where she is going. When she gives me her itinerary, it's as if she is a zombie. I'm pretty sure she is talking to me as I am the only other person in the room, but she looks at the wall when she speaks. Thinking back, I can't remember even the slightest eye contact since BD.
