Shock moment woman exposes ‘cheating’ boyfriend with hidden sticky notes throughout dream holiday – and he has no idea

A WOMAN used post-it notes to expose her cheating boyfriend while documenting their nine-week vacation in Europe.

The anonymous girlfriend posted her videos on TikTok under the username @iknow_girl and went viral with her story.

She began uploading the videos detailing her story on July 31, as she set about exposing her then-boyfriend to social media.

But she did so in a rather unique way.

In every video she’d hold up a post-it note in front of her posing boyfriend in the background, detailing their romance.

She signed everyone with the hashtag “I know”, to confirm that she knew of his unfaithfulness.

The hashtag quickly caught on with viewers, who sussed out that the boyfriend must have been cheating whilst the pair were together.

In total, the girlfriend uploaded eight videos, all with captions attached to them.

The first one read: “I know you all want to hear the story of how I found out the day before I had to leave for a nine-week vacation through Europe with my boyfriend who I knew was cheating on me.”

She goes on to explain how they were first acquainted through the popular dating app, Bumble, but lived in different states.

They ended up doing long-distance for the first five months of their relationship before he confessed his love for her on the sixth.

They took things a step further by deciding to move in together – but not until after he took a six-week trip to Colombia with his friend.

The TikToker explained that he apparently “needed” to, before admitting that it became the “beginning of the end of our relationship”.

“I know that the little things matter, but cheaters will often go above and beyond showing those little things in abundance because of the guilt they harbour,” she continued.

“He really did make me feel super loved and appreciated.”

But it turned out that her former partner’s friend had planned their trip with the sole purpose of helping him cheat on her.

She described this person as someone who knew “the dark parts” of her boyfriend.

Although the woman doesn’t reveal how she found out, she said: “I know that cheaters always get caught no matter how much they try to cover their tracks!”

And it would be the day before their nine-week European excursion that she uncovered the truth about her boyfriend’s Colombian antics.

Understandably, she contemplated not going on the trip, yet she had already reimbursed her boyfriend for all the expenses.

In the end, she decided to go and remain quiet about what she knew.

However, she confirmed in one video, which amassed more than 376,000 views, that she would be “breaking up with him after this trip.”

In order to avoid raising suspicions to her boyfriend about what she was doing, she told him that she was planning to make a video montage of their trip.

Once the trip was over, the TikToker revealed what happened in the aftermath.

While she went back to the US, her then-boyfriend decided to remain in Europe and visit other countries without her.

She added: “It wasn’t until I got home that I sent him the reel I had made, along with a very lengthy message describing how I was breaking up with him.

“He ended up leaving me a 30-second audio message on Snapchat apologising.”

Following the revelation, the woman’s TikTok account was flooded with messages of support from followers of her page.

“You are so mature and handled this a million times better than I ever could have. I’m so sorry and I hope he gets what’s coming for him,” one fan said.

Another commented: “It’s crazy that people walk around this earth just lacking any empathy or care for others. Wow! I hope you are doing well and heal from this.”

A third said: “He is disgusting and I’m convinced he was incredibly insecure and did all this for nothing.”
