Viewers of the ITVBe show saw Harry breaking the news to Bobby during last year's cast trip to Marbella, then leaving the Spanish holiday resort early.
Bobby and Harry then broke up.
Speaking ahead of the new series of TOWIE, Bobby was asked about a time when he felt full of regret: "Trusting Harry… and then him sticking a knife through that trust."
Bobby added that he felt betrayed by Harry, saying: "The fact that I had taken him to Marbella and he was still carrying on and making a fool of me behind my back."
He added that last year's situation in Marbella had been "very difficult" and at one stage he couldn't stop crying.
Thankfully, he appears to have had a much better visit to Marbella this time around, as he said: "I'm always loving life when I'm there. I just love sitting in the sun with a strawberry daiquiri."
Us too, Bobs, us too!
