She cannot win this one however she tries to spin it.
Either:
She was living in the house in Uddingston with the fragrant Peter, as his loving and attentive wife, and had not a single clue that he was buying all this stuff and having it delivered to the house. Or giving it to her family as presents. Nobody believes that.
Or:
The "marriage" was a sham, she spent 99% of her time at Bute House and and had no clue what Peter was up to because they both had separate lives and separate interests. If that is the scenario, then she is pretty much admitting that she has been lying through her teeth for years about her domestic situation.
