Enjoy it and live in the moment. Be happy in the moment. Stay happy.
Remember, It isn't so much how YOU feel, but how SHE perceives you. It would be wise to get a close male friend or two and use them as a sounding board on giving you feedback whether they are viewing you as staying happy or not and telling them you WANT them to point out when you go back to your old ways of seeming unhappy. Some people may SEEM unhappy to others and yet be at total peace inside. Make sure you learn how to put on a happy face as well as a happy attitude... Find male friends that will be direct and honest with you and not tell you what you want to hear. That will help you keep on track with your wife and how she is perceiving you.
