What statistics does Flora Dunn cite to highlight the pitfalls of building a man in relationships?

Flora Dunn from Learn Better, Love Better shares that many women report feeling undervalued when they overinvest in “building” a man, especially when that effort is not reciprocated with commitment or appreciation.

She also highlights data showing that a significant proportion of men switch partners or pursue new options once they “level up” in career, status, or confidence—often after a woman has helped them get there. These stats are used to question whether loyalty in “building” a man reliably leads to long-term security or gratitude.
