Fans watched their relationship hit a rocky patch in the Marbella special, when Bobby found out that Harry had slept with his ex when the two first got together. But Harry recently admitted that he is determined to win Bobby back.
In Sunday's show, the couple – aka Barry – head to the beach to try to fix their relationship.
And true to his word, Harry makes a bid to win Bobby over with a romantic gesture - scattering roses over their hotel bed. Aww!
On Wednesday's show (3 July) the pair had an emotional chat, where Harry broke down in tears asking for Bobby's forgiveness. The TOWIE star later revealed in a behind-the-scenes video that he has blocked his ex's number.
Getting tearful again, he told the camera: "What has happened between me and Bobby is awful. It's the worst thing that's ever happened to us in the whole seven months that we've been together."
He added: "I've moved on, I'm with Bobby. I will win Bobby back one million per cent because we're better than this. I love him so much. I won't let him go anywhere."
Meanwhile, adding more fuel to the fire, Harry's mum Karen comfronts Gemma Collins tomorrow night over getting involved with Barry's relationship.
Gemma is best pals with both men and got caught in the middle in Marbella, where she revealed to Bobby that Harry had met up with his ex during their holiday to Tenerife.
But with Karen blaming Gemma for interfering, is this going to cause even more tension between Harry and Bobby?!
