this is totally not typical and is not indicative of anything but i can’t resist.
i have a friend who is cognitively impaired. she is highly independent but i dont know for sure she could handle marriage. Unless it was to someone like her with supervision/mentors perhaps.
years ago she got engaged to a man from a different state who seemed to be more capable and mainstream. when i heard he wouldn’t travel to our town i was worried that he may not be “safe” for her but was assured this was looked into and it is just wonderful. they bought her beautiful clothes and promised her the world. Eventually, the engagement was broken.
i don’t know who made the final call, but she told me she found out much later that he couldn’t travel because of the ankle monitor he had to wear until his trial for shooting someone in self defense.
