As soon as the wives entered their new homes, they were humiliated and violated. Their petals were torn off, and they were forced to learn what it meant to submit to their husbands as unto the Lord.
While there was no indication that this heavy-handed edict was enforced by law, women were heavily brainwashed. They served out of a sense of duty. Their morals and beliefs became their prison, controlling what they did, how they felt, and how they interacted with their husbands.
This meant many things in different households. But in general, the husband's wants and needs came first. When he wanted a specific meal, that's what they ate. If he decided that it was time for bed, it was time to go to bed. If he told his wife to have sex with him, they had sex, whether she wanted to or not.
Since this was a religious edict straight from scripture, true believers would feel guilty if they went against their husband's wishes. They'd repress their own wants and desires in favor of their husband's. They might even do things to hurt themselves if they were told to do so. Gilead's fanaticism had a way overriding basic logic and the survival instinct. It was about obedience, not taking care of oneself.
Wives were imprisoned physically as well as mentally. If they chose to leave, they could be turned into a martha or a handmaid. They could even be forced to undergo a correction or sent to the colonies. In some cases, they were executed.
They were slaves in the modern sense, and they weren't allowed to choose their masters.
Marriages were based on politics. It wasn't uncommon to see 12-year-olds matched with commanders who had spent decades in the system rising in rank. They could easily be 50, 60, or 70 years old, and more often than not, they were pious men who had convinced the public that they were worthy of their rank.
Men like that, who had been raised to believe that sex was wrong, had voracious sexual appetites. They needed to partake of the forbidden fruit as often as they could. They were also ruthless enough to survive Gilead's predatory hierarchy, where power games, blackmailing, and boardroom chess were common.
Men like that tended to subscribe to a more conservative, misogynistic version of Gilead's belief system. They often managed their women with a firm hand, like a pitbull that needed to be toughened up and shown who was boss.
They tended to be hypocritical. The early commanders would frequent Jezebels. Later commanders were more careful, but their libidos were just as strong. They preferred to force themselves on the women at home.
We aren't sure if physical abuse was standard or a part of Gilead law, but there are many instances of abuse in the series. The men certainly had no qualms about hurting their wives, and many of them did believe that women had to be kept on a short leash.
They would likely cane and whip them, perhaps without provocation to dull their rebellious instincts. In all likelihood, they wouldn't face any consequences for this. Commanders were powerful men, and while they were held accountable for many of their crimes, women seemed to have had their rights robbed from them.
A guardian or an eye could be brought into the home if the wife was found sleeping with another man, but we have seen no examples of them rescuing a wife who was beaten or injured. Women were protected against murder, but a man in a powerful position could find ways of covering that up as well.
WIves lived a horrific existence, and for the most part, there was no escape. They simply had to hope that they would outlive their husbands and be placed into a better home. That was their only chance of happiness.
