There are two things that I can say here. One, yes, sometimes a woman might find an autistic man positive in the early stages of the relationship, especially if, when she's talking to her female friends, the conversation goes like this (Fred is neurotypical, but George is autistic): "Did you watch The Wedding Planner, last night?" "No, I couldn't. We only have the one TV, and Fred was watching the football." "That's a shame. George isn't interested in sports, so we watched it. And George reads books." "Oh, Fred only reads sports magazines and car magazines." But sometimes, if she says, "I want to go to a shoe sale," and one says, "Yeah, Fred went and withdrew $300 and gave it to me, while he sat at home and watched the football," but the other said, "George hates those sorts of things. There are too many people. If he comes, he sits out in the car."
If we think of the 1950s, and probably into about the 1980s, it's not uncommon for couples to divorce once the kids leave the nest for this reason. Say a typical weekday with the family goes like this, "6:30am, husband and wife wake up, husband has a shave and shower, and his wife gets his breakfast, 6:55am, husband comes out and has breakfast, his wife rouses the kids at 7:10am, husband brushes his teeth and kisses his wife good-bye and heads off to work, he arrives at his office at about 8am, and the kids leave for school at about that time, and the wife has her shower, and sees to the laundry, cleaning the house and the like. The kids come home from school at about 3:30pm, and the wife supervises their homework. The husband arrives home at about 6:30pm, has a beer and reads the evening paper, and at 7:10pm, his wife places his meal on the table in front of him, at 7:30pm, he goes and sits in the lounge and watches TV and retires to bed at about 10pm. Then, when the man retires, instead of thinking, "Okay, let's enjoy life. Let's take that road trip we've always talked about. Let's take that overseas holiday," the couple think, "Is THIS who I married?" and they have grown apart.
