A lot of the conversation centred around Richie "not being there" for Alex in a time of need.
As of right now, we don't know what it was that Alex was going through, but there was a lot of underlying comments that has led fans to believe Alex had to endure something very intense without Richie.
"When I needed you the most, when I needed you - and you know what I'm talking about," Alex said to her ex.
"Look Alex," he replied, "I've explained to you in length, how are you supposed to umm… how am I supposed to make dates and jump through hoops when it's impossible when you're changing the goal posts every couple of days."
The single mum then confirmed, "I'm talking about a single time."
"I know exactly what you're talking about Alex and I know exactly what you're trying to say and it's not like that. We talked about this on the phone for hours in length," he said in response.
Alex explained how they spoke on the phone over something she was so "hurt and upset" over this specific incident, but Richie claims that this incident 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," she said.
"Because I was away working, Alex. I was on a mine site," Richie hit back.
Alex hit back. "So you couldn't get on a plane knowing where I had to be and what I had to… I was left alone to go through something massive that no woman should have to…"
"Like I said, Alex, I've come to terms with it – I'm at peace with all my actions," Richie said.
