I think you're being to technical (and this may be hypocritical coming from MISTER technical over here) on your definition of communication. Yes, some people don't communicate very well, but without communication, you can't have a relationship at all.
So if someone wants to be an introvert loner that doesn't discuss things, but sits in their room and doesn't talk to anyone, then you CANNOT HAVE a relationship. I'm assuming that since they lived with each other for so long, decided to get married, and NOW they are having problems, that in the past they have at least argued, discussed matters and worked things out.
I may be wrong. But if I'm wrong and there is no communication, then there is no marriage.
