Here's exactly what was said int he intense confrontation between Richie and Alex:
"I barely saw you. I needed to see you more," Alex said throughout the conversation, to which Richie argued that she had continued to "move the goalposts" and had barely visited him in Perth.
"[You weren't there] when I needed you most - when I needed you - and you know what I'm talking about," Alex said.
Richie responded: "I know exactly what you're talking about, and what you're trying to say... [It was] completely out of my control."
"How is it out of your control to get on a plane and come and see me during a really personal time that involved both of us?" Alex questioned Richie.
When Richie brought up how he had been dumped by text, Alex responded:
"Do you actually want to go there, Rich? Because I feel like a lot of people would have an opinion of a woman being left alone to do something that involved both of us."
"Don't beat around the bush Alex... Just say it, because you're not going to like what I have to say," Richie replied. "What you said to me blew my mind, again, I've had to come to peace with this."
Alex responded: "You knew you couldn't salvage it, because you knew that after what happened, when I was left alone that was something massive that no woman should have to go through."
"You wanted to do it... You wanted to go down that path because you told me you wanted to focus on your AFL career. That was part of it," continued Richie, which Alex denied.
"I don't have an AFL career to focus on, I don't even know what you're talking about AFL career... You're going to sit there and honestly say to me that all of that was my decision?" she said.
"Yeah we talked about it because you know Alex you're a mother... I know that, clearly. I spoke to you at length about that because you've gone down that path where you know what is involved with that. I supported you and your decisions," Richie said.
"But where were you?" questioned Alex.
"What am I supposed to do click my fingers and just appear for you? You changed the 'goalposts' so many times," Richie fired back.
"If you're a man and you're in that situation you move mountains to be there," said Alex.
The heated discussion, however, ended with them each giving their blessing:
"Like I said I've come to peace with it Alex, and I'm fine with it. I'm happy that you're in a good spot, that you think you've grown as a person. I didn't want to get into any salacious details, and I've stayed quite composed," Richie told Alex.
"I think we're doing a good job. It is bizarre... but I want you to be comfortable. I've put it to rest, I've moved on and I think you're a good person and that you deserve to be here and find someone potentially. I just didn't want it to be uncomfortable," Alex added.

Earlier this week, Alex revealed that she signed on for BIP after producers told her Richie wouldn't be apart of the cast. Speaking to 90.9 Sea FM’s Heather, Dan & Ben show, Alex shared: they actually told me that Richie declined three times."
Speaking of the moment she is shown reacting with surprise about the presence of her ex, Alex was asked if it was all a big "stich up".
"That is the moment I clocked him," she recalled. "They said I was in the clear"
The 31-year-old continued: "I said I didn’t want to see him again on those terms and in that kind of environment, and they said he’s declined, we don’t think he’s interested.
"But, apparently, 48 hours before flying out to Fiji he [changed his mind]."
