Both were keen to give their relationship a go on the outside world, but Heidi had said they must “put their swords down”.
They moved in together but Mike decided he could not make her happy, with Heidi saying they did not share the same values.
Since leaving the series, Heidi has remained friends with some of her co-stars, including married couple Jules Robinson and Cameron Merchant.
She is an ambassador for the charity Inclusive Kids, which supports disadvantaged children.
The radio star is still also hosting the 91.9 SEA FM station, and she appears to be single.
