People ultimately want shared experiences and a shared sense of purpose when they marry. Unfortunately, there's a lot of spouses out there who simply want someone to take care of them and have no real desire to be friends with their partner much less go anywhere or do anything with them. Those are also the people who are the most shocked when they discover their spouse is filing for divorce. If your entire life revolves around YOUR job, YOUR hobbies, or YOUR friends, your spouse is going to be pretty lonely - especially if you split all your time at home between the bed, the television, and the computer and refuse to go out for an occasional meal or a even a walk around the neighborhood.
