Speaking on his podcast, The Babble, Matty said that the weeks immediately after the finale airdate are crucial to any Bachelor or Bachelorette couple because it's the first time you can be public about your relationship after months of hiding around.
"There is almost a two or three month gap from when they film the finale to when you're [publicly] together," he explained, saying that it can be awkward trying to adjust to normal life after months 'in hiding', so it's important to spend as much time together as possible.
"The weird thing with Matt and Chelsie is, straight after the finale [aired], he went away, he went to the UK," Matty said, as though this could be a reason - or at least a sign - for things not ending well.
"Maybe Matt didn't realise how important that time is? Because you can finally get to be together and have that relationship out in public," he added, before going on to say that he and Laura thought something was wrong when Chelsie and Matt pulled out of the Melbourne Cup.
"We were at the Melbourne Cup and Laura and I were really excited to see Matt and Chelsie," he said. "We were heading to the Channel 10 marquee and we spoke to one of the publicists and we said, 'Hey, are Matt and Chelsie here?' And they said, 'Actually they're not coming anymore."
"We didn't know why they weren't there, but there was a thought that maybe they weren't together."
