well you are allready one step ahead with Jo where my wife is concerned
At least Jo somewhat appreciates the old girls
No amount of work ,grovelling or extra activities equates to blitz time for me

At the end of the day you just have to make a stand and do what you like for a reasonable and shared timeframe per week and cover yourself (as best as you can)for the inevitable hail of flak and ear bashing

With Jo you could make it family time and get her to work on hers as well
