Sam and Tiff are no strangers to drama when it comes to their relationship, and both have come under fire for being unfaithful in the past. However, fans recently learnt that Tiffany hadn't been completely honest about what happened with her and another guy that time in Hong Kong - and when she revealed to Sam it was more than just a kiss, he was devastated.
Sam had told Tiffany he 'despised her' for lying to him and left fans wondering whether he was going to end their relationship for good. But, in last night's episode of the show, we saw Sam tell Tiffany he thinks they can work through it and the pair appeared to get things back on track.
While Tiffany had admitted seeing Sam so upset was like a "dagger to the heart", he was contemplating what to do about their romance. Sam told pals Jamie Laing and Olivia Bentley that he wasn't sure he and Tiffany could stay together because it would mean him feeling insecure and not being able to trust her, meaning many more arguments to come.
However, he appeared to have a change of heart and later met Tiffany to reconcile.
Sam told her: "I've literally been going through so many thoughts and emotions in the past week. There has been so much anger, that I didn't even know I could feel. You've hurt my pride so much and you've embarrassed me. Tiff, how am I going to trust you again?"
"I've made mistakes," she said. "People make mistakes and they don't do it again... I know you don't believe me, but I know I wouldn't do it again. The only way I can show you is by not doing it and I won't do it."
"Why would I put myself through this, you through this ever again?" Tiffany continued. "This has been the worst week of my life."
Sam told her that her lying to him was "unforgivable", but he was willing to try: "I want it to be forgettable, I think the forgiveness will come as well."
"I don't want to think about it. I don't want to lose you," he added. "I won't. We're going to get through this. I hope."
When Tiffany said she thought Sam had come to Toff's cheese and wine party to break up with her, he told her: "I can't... You are the love of my life and I don't want to do that."
Following the episode, Tiffany took to Twitter to tell fans she was feeling "very grateful" that Sam had been willing to give their relationship another go.
She tweeted: "Feeling very grateful and happy and I know I'll never make the same mistake again. Got my best friend back."
Tiff also shared a new photo of herself and Sam, gushing alongside it: "My favourite person."
Sam, meanwhile, tweeted: "She makes me happy, and that's all that matters to me."
