He got a different perspective on life, what kind of BS is that, he left out the real truth, he just wanted to be free again. Marriage can feel like shackles on your feet. It’s just not for everyone long term. My guess is that he felt that way for a long time after being pressured by society rules of marriage is a must since you have been together for so long. On the other hand maybe it was her fault for letting him fall out of love with her, was she putting out, looking good all the time, was she cooking, many issues underlying that we will never know. I am going to get you all a copy of "How to be a Wifey" book.
