The comment floored Hayley, a Melbourne finance broker, and she started to sob.
"It's not recovering, it's recovered," she cried. "I'm not my past. You are saying it like it's a bad thing that you are matched with me because of my past.
"I am not that person any more ... I've done so much f***ing work on myself to get to where I am today."
"What a mess," she added, as the other couples watched on looking upset and shocked.
WATCH: MAFS' Hayley was a former drug addict
Relationship "expert" John Aitken intervened to try and restore some calm to the situation.
"You take a moment Hayley. David, this is for you," John said. "Hayley has, in the past, had issues with substances, but not now ... David, you can't judge her on her past, she's not chained by it."
Hayley added: "I am the biggest f***ing bogan, money does not mean a thing to me."
David looks as if this is the first dose of self-awareness he has ever received.
Dusting herself off, Hayley apologised for commenting on David's wages.
"I feel terrible, Dave, I'm sorry, I'm so sorry," she said.
"For her to say that to me in front of everyone, that means a lot to me," David said.
Hayley added that she hopes her appearance on MAFS can give other drug addicts hope that they can "get their shit together too".
But the most shocking part of this whole to and fro is that both voted to "stay" together in the experiment. What the actual?
These people are a sucker for punishment, but we suppose they have their eyes on the teeth whitening endorsement prizes.
