"Hypergamy never sleeps" is a common Red Pill expression, meaning women's instinct to be with a higher status or wealthier partner never ceases, regardless of how good the current relationship is.

From my experience this only partly true, and it's more about her attraction level as to the specifics of what makes it go up or down. Subconsciously perceived inner "strengths" such as Ambition, Courage, Confidence, Charisma, Independence, Status, and Self-Esteem make her attraction go up, and the antonyms of those qualities make her attraction go down. "Frame" to me would be another way of describing a combination of the above.

Therefore there is no "Monkey Branching" as long as her attraction level is high. To restate, they don't care about other men or have feelings for other men when their attraction level is high.
