When Woman's Day contacted the Bachelor In Paradise star he acknowledged they were together after the show, but he insisted they had since parted ways.
However, friends close to Tash tell us she and Michael are still in touch and they're worried she's set for further heartbreak, especially after they were snapped together in what looked like a heated argument last weekend.
Friends of Tash say they were wary of Michael from the get-go, fearful the Queensland-based real estate agent wasn't taking the romance as seriously as he should after failing to go public with the relationship.
"He told her he loves her but he wouldn't acknowledge their relationship to anyone!" one friend tells Woman's Day.
"We're worried he's stringing her along. He says he wants to find love, but it seems he's more interested in fame than nurturing his relationships."
It's not just Michael's hesitance to sing his love from the rooftops that has Tash's friends seeing red.
"Tash was devastated when photos of Michael and Sarah Roza [from MAFS] came out, but he insisted it was a publicity stunt!" another friend tells, adding those close to Tash fear Michael puts his public profile ahead of his personal life, even if it compromises his relationships.
Tash certainly didn't look happy when the pair were seen fighting on a Melbourne street soon after.
Rather than admitting a lover's tiff, Michael once more shut down rumours of a romance after the pictures emerged, insisting the pair are "just good friends".
"I am 100 per cent single. Me and Tash did spend some time together after the show. We were sort of seeing each other, but we're not any more. It didn't work out. We still talk as friends – it didn't end badly," he tells Woman's Day.
Now, those close to Tash are warning her to be careful as they suspect Michael isn't as set on finding "love in the real world" as he claims.
"Last month he told his Instagram followers he hoped to find love in the real world… and he had the chance!" says a friend.
