I’ve been married 30 years and it’s had its ups and downs. Almost got divorced 15 years ago when she checked out over an emotional affair with her friends husband. (I think they had an open marriage) but therapy and hard work made us together again. The kids are gone and you begin to understand why people divorce. I bet most of these couples were well off and a divorce isn’t going to wreck either one financially. Women stay in crappy marriages for the kids or financial reasons. I’m my extended circle of friends there have been a couple of divorces but they are tertiary level friends. They were both abusive relationships after 25+ years of marriage. Otherwise I think most couples either get along well or tolerate it. But from time to time I think it would be fun to just do my own thing and I’m sure my wife thinks the same thing but we both realize it might be fun for a while but will probably get lonely real quick.
