In the 19th year of what I thought was my very strong marriage, my wife looked me in the eye one morning and said, "I love you but I'm not in love with you anymore." I thought it was a cliché. I thought it was a joke. I thought it was very sick humor. Over the next 18 months, I learned that my wife was sincere: she wanted out of our marriage. This despite three children, a beautiful home in Pennsylvania, a marriage that friends often cited as a "perfect" marriage. In I Thought We Were Happy, I explore what happened to my so-called ideal marriage, what went wrong, why I failed to heed the warning signs, its actual disintegration, the efforts I've made to put my life back together. The story is honest, raw and reflective, the writing candid and emotional. Along the way, I explore why I loved-and continue to love-this woman who walked out on our marriage after 20 years. While many women have written poignantly about broken marriages, few men have tackled this subject in non-fiction form. I may be from Mars, but I suspect that inhabitants of Venus will be as interested in this story as my fellow Martians. While the writing reflects the anger and bewilderment I felt at times, the only person I put under the microscope is me. Along the way, I share the wisdom and counsel of the therapists and friends who helped dig me out from down under, most of them women.
