Need support navigating the change in my marriage

[G8r]

Stopped talking to W and soon as she got on iPad to text with om. She noticed and said I guess you don't want to talk to me. I ignored comment and walked by. Few minutes later D3 said something really cute that I chose to share with W. She replied that I'm surprised you shared that. I again chose to ignore her passive aggressive comment and went back to what I was doing.

As I was reflecting, I noticed that by doing this I am shaping her behavior through process of giving and withholding positive reinforcement and the baby steps can be seen as successive approximations to the desired behavior. Where is the chocolate? Sheldon Cooper on Big Bang Theory would be impressed.

Anybody else notice the similarities between DBing and operant conditioning and classic conditioning?
