How can I tell if this is working?

I have basically "gone dark" with my wife. She is still in the house but moving out Saturday. What I am doing is only communicating with her through text or email. I don't speak to her unless she speaks to me first. I'm not trying to be a jerk, but she said she wanted me out of her life and so I am trying to honor that. I don't know if she thinks I'm mad or whatnot...I do not feel it's my problem to worry what she thinks about me.

It's been two weeks since the bomb was dropped. Since I have cut her off she seems to be more grouchy than usual. She is going to that friend's house and spending the night there. Yesterday, she came into the house, laid down in the bed and talked quietly to someone....which I don't recall her ever doing that before. She looked like she may have been crying, but it could have been her face was red...I couldn't tell either way, so I guess it's a moot point.

Last night my neighbors were walking by my house and I struck up a conversation with them. My wife ignored them for awhile and then got up and started talking to the neighbors wife while I talked to the hubby. Both of our wives left to go get cigarettes and to check out my wife's new car. She's been very short with the neighbors lately and having nothing to do with them...unless she wants something, like her hair cut. The other day I was talking to out neighbor lady and when I came home my wife asked, "so, is she your buddy now" in a annoyed way.

Today my wife came home at 7:15 am to take my daughter to school. Of course, I was the one who got her up and ready to go. I'm the one that put her to bed to go to sleep last night...yep, she was at her friend's house. My wife came home and said hi to me. I paused for a second and said hi back. My wife then told me her friend was coming over...which I responded by saying, why would i care about that? My wife took a shower and came out with the gorgeous lipstick on. I am a sucker for lipstick. I couldn't tell if she was wearing it for me or for her friend, but she doesn't wear that dark lipstick often. Then...they all went out for breakfast.

Is it too early to tell if I'm on the right track? She's already told my neighbor that my changes were "too late", so I know she's noticed something. I just can't tell if her reactions are due to me, or not. How do you know?

I've been good thus far with everything. Yesterday I felt like things were going good. I felt like I was making progress; even to the point that I felt the urge to try talking to her about us again...I refrained. I'm so confused. Why the lipstick, why is she suddenly talking to the friends when I started talking to them? I'm not saying anything bad about her to them...I have told them both that I don't want them in the middle, there are two sides to every story.

The questions are endless. I'm sure I am analyzing too much. It's been the longest that I have gone without talking to her. I'm just so confused.

Can anyone give me advice and point me in the right direction if needed. Encouragement would be great. Or, you can completely rip me up and tell me I'm being stupid. Whatever works.
