I agree with your assessment of TxHubby approach. But from my own experience I know it's a hard concept to implement without turning cold. I had to scale back on his approach, because I was ghosting my wife and I realized that I wasn't prepared to go all in yet. I think a lot of people here see detachment as going cold, while I have realized that it's about moving on with your life, while still showing love and respect for a person, that has disrespected you. You don't allow them to disrespect you any more.
