In my opinion the important thing is not that your wife thinks she's lost you, she needs to KNOW that she's lost you. That doesn't mean that you stop doing housework; the housework has to be done. What it does mean is that your actions and attitude tell her that you're ready to move on and you'll be just fine without her. In other words, you have a life and you're going to live it to the fullest and you don't need her in order to do that.
