I read further in one of the articles, and she wasn't on the toilet for two years - but she had a phobia about coming out.

She would shower and change clothes and all - but wouldn't come out. It was the last 2 months or so she was actually on the toilet. I suppose the lack of hygiene then more than made up for the past 2 years.

Maybe he waited this long because he couldn't stand the smell any more.
