In the unsuccessful marriages that I've witnessed I've seen fault on both sides. Yes, typically the women were the ones that looked at their husbands as projects and wanted to "fix them." In some cases the men were conditioned to think they had to change or wanted to be changed because of issues with they had with their sexuality.

If you can't be yourself with something that is themselves too, then marriage doesn't work well.

Look, I get it. People do change over time. My partner used to like Bluesgrass music and now she doesn't. Was that a dealbreaker for me? Not at all. If she changed her value system mid flight, then yes it could very well be a deal breaker.
