I don't think it's that simple. Sure, it's true that the lesbian divorce rate is far higher than the gay male divorce rate, and sure, it could be from personality differences between men and women. Women do indeed score consistently much higher on neuroticism (+half a SD from a 26-country review [0]!), but they also score substantially higher on two of the other FFM traits (agreeableness and conscientiousness) which you would expect to reduce divorce. Like a sibling comment mentioned, gay men earn more money, which reduces divorce rates. Then there are all the factors that are hard to put a number on, like the stereotype of "u-haul lesbians" - which the lesbians I know consider to be an accurate stereotype. That would obviously play a large role here. Married gay men also have a far higher rate of open marriages.

Also, if anyone has some quality data on this subject, I would love to hear it. A lot of the data out there is from tiny and poorly-designed "studies" or public datasets rehashed by ideologically motivated organizations, which makes sense; it's a very emotionally charged and political subject. The UK Office of National Statistics has some good data: https://www.ons.gov.uk/peoplepopulationandcommunity/birthsde...

Other interesting hot button gender war topics: gay men vs gay women vs straight couples collaborating and communicating, rates of adultery and abuse, and adoption outcomes.

n.b. anytime you read something on the subject, you need to take note if you are reading statistics normalized to the sex ratio of same-sex marriages; for example 78% of same-sex marriage in Taiwan is between women vs. 45% in Costa Rica and 53% in the US. https://www.pewresearch.org/short-reads/2023/06/13/in-places...
