The Bondi-based beauty showed off a cute tattoo on her derriere Woman's Day quoted a source as saying that Martha was 'blindsided' by the public backlash she faced in recent weeks. Apparently this onslaught of 'trolling and criticism' has taken a toll on her relationship with Michael, 28, and it's only matter of time before they call it quits. 'They both looked really uncomfortable and stressed,' said an onlooker who saw the couple at Chatswood. 'The chemistry you see on TV just wasn't there.' Meanwhile, a source close to Martha claimed she is 'struggling' with the fact she was edited as a pot-stirrer and 'mean girl' on Married At First Sight. 'Things have gone from bad to worse [for Martha and Michael] since the finale,' they said. 'She is in a really bad place... and has struggled with all the criticism.' Martha's financial situation has also reportedly put a strain on their romance, after she revealed last week she has been unable to work as a freelance makeup artist due to concerns for her safety. An insider claimed she has been 'depending on Michael', adding: 'Their relationship has taken a major hit with the pressures from the show. I don't think they'll be able to sustain this at all.' Michael and Martha agreed to stay together during their final vows on MAFS, despite having doubts about getting involved in a long-distance relationship. Martha is based in Bondi Beach, Sydney while Michael worked as a schoolteacher in Melbourne until recently.
