This is quite easily the worst response I've ever read in my life.
Had I followed this advice, I'd still be suffocating in a relationship that ultimately was not where I should have been. I would have never met my true soulmate, I would have wasted my life feeling frustrated, miserable, and worthless.
And for the record, staying together with someone who makes you miserable does not do a child any favors. I'm talking from experience. My mother was a suicidally depressed alcoholic for most of her adult life, and my father didn't want to talk divorce until I was out of the house. My parents staying together for 30 years meant that I had the pleasure of checking my mother into a detox program at the local hospital after a suicide attempt (which happened as a result of her trying to quit drinking cold turkey and almost going into heart failure as a result).
After my parents divorced a year later, my mom got sober because she was finally free from the man who drove her to drink, and could begin her life anew; She transformed herself into one of the most amazing people I've ever known. She's fun, joyful, and full of life in a way that would have NEVER been possible while married to my father, who was emotionally volatile and had explosive rage issues that were terrifying. I would give anything if they'd divorced years before they actually did.
