For older single guys (over 40), what's your view towards marriage? Is it worth the bother for you?

I am divorced. And story b sounds just like my ex wife. But I really wouldn't trade it for anything. We adopted 4 kids. Which I wouldn't have had. They are my life. I would do anything for them. Even though marriage sucked. I would do it all over again for my kids. So I guess story b I would pick. Anyway.
