"It just didn't work for them outside of the show," the source told the magazine.
"Heidi found out Mike had felt pressured to say he loved her and couldn't deal with it."
It's also been rumoured that Mike has already moved on from Heidi with Gold Coast-based model Casey Stewart.
In an interview on Nova's Fitzy and Wippa show this morning, however, Mike denied claims that he's split from Heidi since their final vows.
Either way, we seriously can't wait for next week's reunion special.
