"Marriage is hard!" "Marriage is work!" "My husband is a slob who never does the dishes!" "My wife nags me constantly to do the dishes!" said every married person ever. Marriage is challenging, according to most (honest) married people. But it has many benefits, as well, or people wouldn't remain married despite—and throughout—these challenges.
Someone asked long-term married couples of Reddit: "Whats was the worst low you've had and why didn't you leave?"
From Suspicious_Sassafras:
11 years married. Worst low was he was being a complete a**hole (Screaming at 8 y/o) to one of my younger kids and when daughter (18) stood up to him he tried to sell her dog as punishment. Didn't leave him because I recognized a PTSD episode and got him help. I think it's important to recognize why a behavior is happening. This was NOT his normal behavior. He's former police officer and this was when he had to walk away from a career he loved. It was HARD, but he was willing to accept help and has stayed in therapy for 2 years now.
