I have been through what you just expressed. The only thing I can suggest which is working for me and mine, is to keep the lines of comm tunication open. Don't overdue the talking about your needs, however, as that will become an issue for her. Talk to her about your needs as you feel you need to get things off your chest, but again, do this with some 'space' in between. Definitely continue to reasure your wife that you are still the man she married. Go out of your way to do chores, and all the things you have done before. Also, make sure you continue to tell your wife how much you love her, and how much she is the number one person in your life.
Put her needs ahead of your own. Be sensitive to her wishes but do talk openly and reach compromises about things which you feel are important to you.
While you need to be true to yourself, you also need to be understanding about the emotions and sensitivities your wife is now feeling due to the shocking new news you have just delivered to her.
Again, open and honest communications are the key to your future with your wife and to your future success and understanding with one another. Good luck!
