> I know there's 0% chance that my wife and I will get divorced You share this mindset with every divorced guy I know, including myself. Men just don't see it coming.
Men don't see it coming because they don't care. Quite frequently men are in bad relationships that don't affect them much but they generally don't walk away. Women pull the trigger when they can't take it anymore.
Unfortunately, life can be complicated, e.g. family member went through undiagnosed schizophrenia for many years, one can imagine how that upset the marriage assumptions prior to the mental health issues.
