The "other woman" is liberating herself from men

The argument

True liberation from oppressive social and cultural structures means putting yourself, and your needs, before other concerns. Women who enter into sexual relationships with partnered men are acting purely in their own self-interest. After millennia of being limited by oppressive patriarchal structures, this behaviour represents strength and female liberation from these long-standing norms. This is an enlightened way of being. Whether the man chooses to respond is his decision. But a woman's expression of sexual interest in this context should be read as empowering.

Context

The focus of this question must be on the affair partner, rather than the male. When a woman chooses to engage in a relationship with an attached man, she is the agent defining the situation. The man is simply complicit in her decision.

Premises

Counter-arguments

While this may offer an alternative reading into the female motivations for infidelity, they shed no light on why men cheat. While the woman may actively tempt the man, she cannot be held responsible for his actions.

Rejecting the premises

[Rejecting P1] Acting in one's own interest and being liberated are equated by stipulation. Liberation is ordinarily understood as freedom from constraint rather than as the priority of one's own needs over everyone else's, and on the premise's definition any self-interested act would qualify — including the man's, which is the thing the argument is supposed to explain. [Rejecting P2] The counter's objection is decisive and unanswered: this is an account of one woman's motives, while the position claims to explain why men cheat, so even if every word were granted the conclusion would not follow. Treating the man's response as simply his own decision also concedes the point, since it locates the choice with him rather than with her.
