Excellent job, Alpha. My only caution to you here would be to let you know this is going to take a LOT of effort to build these new "muscles" (habits) into the new-and-improved Alpha, and there WILL be setbacks along the way. Some unforced errors as the "old Alpha" rears his emotional and reactionary head, and definitely some further testing and button-pushing by your wife.
Give this time, and BE CONSISTENT. And measure your success by the longer-term trend and not by every single day, and you WILL see success, of that I'm certain.
It's what "loving detachment" looks like. Feels good, doesn't it?
