But when it came to citing the split on the grounds of his suspected adultery – although there was no evidence of infidelity – she was stunned to discover that the law says adultery can only happen between a man and a woman.
She told Sheron Boyle for the Sunday Mirror: ‘I’ve always believed he cheated. The law now accepts same-sex marriage.
‘Divorce needs to adjust for same-sex affairs.’
Sara added: ‘The law is out of sync with 21st century life.’
Instead, the couple reluctantly agreed to divorce in January for ‘unreasonable behaviour’.
Now the mother-of-three is campaigning for a change in the divorce rules, demanding that the process should be the same for all marriages.
More amusingly, is it the same the other way around? A heterosexual shag is not adultery in a homosexual marriage?
