Home and Away's Rose Delaney delivers upsetting news to Xander

 What does the future hold for Xander and Stacey?

Home and Away has revealed the outcome of a major dilemma for Rose Delaney.

Rose faced a tough decision on Australian screens this week, as she caught her brother Xander's girlfriend Stacey Collingwood cheating on him.

When Stacey first started dating Xander, she made it clear that she doesn't enjoy monogamous relationships and likes to date different men at the same time.

However, later in the relationship, Stacey promised Xander that they could become exclusive.

This week, Rose was left in a difficult situation while out on patrol in her role as a police officer.

Rose caught a man and a woman hooking up in a car, but when she ordered them to stop, she was shocked to discover that the lady in question was Stacey. Stacey had even cancelled a date with Xander to pursue things with her new love interest.

Once off-duty, Rose urged Stacey to be honest with Xander about how she'd cheated on him. She was then left frustrated as Stacey begged for her silence, claiming that it was just a one-off mistake.

When it became clear that Stacey had no intention of coming clean with Xander, a reluctant Rose was forced to do the honours instead.

Rose explained: "I caught her last night in a car with some guy – that's why she couldn't make your date."

Xander immediately believed Rose, pointing out: "If you hadn't caught her, I'd still be in the dark. I'm such an idiot. She told me that she couldn't do one-on-one – I should have listened to her. Why didn't she tell me if she was struggling?"

Later, when Stacey paid a visit to Xander at the pier apartment, he made it clear that he knew what had happened. Are they about to go their separate ways?

Home and Away fans in the UK will see these scenes on Channel 5 in March.

Home and Away airs weekdays at 1.45pm on Channel 5 and 6pm on 5STAR. First-look screenings air at 6.30pm on 5STAR and the show also streams on My5.
