Girlfriend, 30, is heartbroken after her boyfriend was cheating via his secret Facebook page

A devastated woman has revealed the moment she discovered her boyfriend of three years was cheating on her after she found his secret Facebook account.

Lilly, from Perth, Western Australia, met Dave through their retail job when they started having a few steamy ‘on-shift trysts’. 

The 30-year-old woman said their serious relationship was going well until she decided to clean up his place while he was out having drinks with his mates.

‘I accidentally bumped the mouse of his computer and the screen lit up. Facebook was open but Dave had a different profile picture,’ she told Take 5 magazine.

At first glance, she thought he looked ‘cute’ in the snap but she quickly realised Dave had his relationship status set as ‘single’ on a whole new profile account.

She quickly discovered messages between her boyfriend and his lover who wrote on the same day: “Can’t wait to see you tonight, babe. I’ve missed you”.

‘I felt my heart break into a million pieces. I looked through his inbox and discovered dozens of flirtatious messages from other women. My face turned red as I realised he’d been having multiple affairs for over a year,’ Lilly said.

She decided to wait for him until he returned home at 2am.

‘He found me in the lounge room, fully dressed and holding my bag. “I know where you’ve been, you b***ard… It’s over”,’ Lilly said.

While she stormed out the door, Dave didn’t say a single word.

Three months on, Lilly said she’s moved on from their breakup but admitted she was still reading his ‘salacious texts’ from multiple women because he never changed his password.

And while Lilly said she wants to tell his new girlfriend about his ongoing affairs, she’s afraid he’ll know she’d been stalking him online for months.

‘What I’m doing is wrong but after the way Dave treated me, I don’t regret a thing,’ she said.
