Are the lesbian marriage divorce rates evidence that the modern Western woman is unhappy?

Think about it. Lesbian marriage divorce rates are the highest in society, even higher than heterosexual marriages. Significantly higher than gay marriages.

Women initiate divorce 70% of the times in heterosexual marriages. The reason given for that is that women get the raw end of the deal in marriages, whereas men get the good end; so that’s why women are more likely to initiate divorce. Hence the man in the marriage being the problem.

Take the man out of the equation, what rationale can be given for lesbian marriage divorce rates being highest in the country? Maybe the more plausible conclusion is that the modern western woman is unhappy regardless of circumstance, entitled, and not willing to keep a commitment?
