Sleep with your dead wife?

I read an article recently about a South African man who sleeps beside his dead wife at weekends. He didn't want to be parted from her after she died so he has built an air conditioned mausoleum for her in his garden. On friday night through to Monday morning he sets up home there and lives "normally", except he lifts the lid of her coffin and has her join in with life. He doesn't have sex with her! Her skin is now shrunk to the bone as the decomposition process runs its course. Could/would you entertain such an idea if it was your loved one or you? Is he mad or sad. Or is this entirely acceptable to you?
