Would it be hard for a prosperous, handsome man to fall in love with a woman with Downs' Syndrome?

Two houses up the street from us live a nice looking man, a golfer, who married a tiny woman with Downs’ Syndrome. She’s not only peculiar, you cannot understand what she’s saying. By peculiar I mean she was walking down the street carrying a rake in 98 degrees. I said, hoping to understand her reply, “what are you doing?” and she said, “I like to pull weeds. Weeds.” But she wasn’t going to their house. She is always the first person to ring the doorbell on Halloween when it’s barely dusk outside. I wonder how they communicated when dating? She walks all over the place in the hottest weather and thus has a cute figure. I admit to waving to her but dread her wanting to chat because it’s like she doesn’t speak English. I guess he recognized she had a good heart but how they communicated is a mystery.
