We need to know how to interpret the entire series of illustrations in Matthew 5:17-48, before we can be confident we are understanding the specifics of verse 32. The illustrations are part of Jesus' explanation of how to interpret the law, and that he has come not to abolish the law but to destroy the evil and false (legalistic, outward) method of interpretation practiced and preached by the scribes and Pharisees:
In the context of a culture of patriarchal society and religion, whether the woman commits or is the victim of adultery, the man who divorces her bears responsibility[2]: any call to obedience must be first be followed by the man who has greater power and responsibility in the marriage.
It is unlikely that the woman is being singled out for condemnation or exoneration in this context, and the broader application of the specific command would apply to her in a secondary sense. A contemporary application would need to take account of the culture of the day, for example whether a woman has the legal right to divorce her husband.
