Reading the article, the man's wife just stopped wanting to have sex with him, which had emotional connections for him (some people are like that). So he lost part of that emotional connection and made it with the doll he started having sex with. Maybe it's an American thing but there is couple's consoling. I mean, the wife admits in the article that yeah, she just didn't want to have sex anymore, even before the doll. Maybe he should've been trying to find out why that is. I mean, if he's happy, and she'll deal with it (as he's not asking her for sex anymore and that's what she wanted) then I suppose leave it be, but I would at least try to figure out why his wife started getting distant prior to the doll.
