Okay, here’s the thing: If women are miserable nags and men are lying cheats and marriage is so horrible that you’re constantly asking yourself “Why did I get married”… then why are you still married? Get a divorce. Don’t get married in the first place. It’s not required. Who is forcing you to live a life you don’t want to live with people you don’t want to live it with?
The answer to the titular question is actually not that hard.
