Pselletes, who shocked viewers with his regular arguments with his partner on the Australian version of the reality television show, said that watching himself on TV "scared" him because he had no idea how chauvinistic and aggressive he could be towards her.
"I'm disgusted with my behaviour. I'm ashamed of myself. I saw some footage of me on the show and I scared myself," he told Woman's Day magazine.
"I'm the psycho, I'm the big mouth. She's done nothing wrong. Anastasia, regardless of what people may think right now, means the world to me. I have verbally abused her and I am very apologetic. I am trying to change. I could never on purpose hurt her, physically or emotionally and if somebody else did, I would be the first person to defend her."
Pselletes also admitted that the show might be "hard" for Drimousis's parents to watch but said that he doesn't want them to think that he is "nice" to them but different "behind closed doors".
"I can't change everybody's mind about me but those two [parents] are the most important," he said. "I look into their eyes and I see a bit of disappointment. They won't tell me to my face, they are trying to be nice and keep things calm, but there is a conversation to be had and I will face that and show them I will change."
Earlier this week, renovation series The Block premiered on Channel Nine and bickering contestants Josh and Jenna admitted that they were "worried" that they would receive the same backlash as Pselletes and Drimousis.
The Australian version of The Amazing Race was first announced last year.
