Things can really go sideways when a couple is supposed to go on vacation and then…BAM!, one person finds out that their partner is cheating.

It gets ugly!

But one woman decided she was done with the guy who is now her ex after she discovered his dastardly deeds and she ended up getting revenge on him.

It all started with a flight confirmation…

Cheat on Me and No One Goes on Vacation.

“My ex and I used to go to a Cancun resort every year with a bunch of our mutual friends.

I found out my ex was cheating on me when I accidentally got a flight confirmation email that he booked tickets for himself and the other girl.

It was rough.

She tried to be civil, but the guy acted like a real creep and wasn’t exactly accommodating.

Tried to have a civil breakup but he refused to pay me for the Cancun vacation that I had already prepaid.

I tried to get my money back but he refused.

After our breakup it took me several weeks to find a new place to live and move my things out of his house.

So she did what she had to do and it looks like the guy found himself empty-handed at the airport.

Oops!

On the last trip to the house I asked him one last time for the money and he again refused.

So I “accidentally” packed his current passport in my last box of things and left my expired passport in its place.

Since he has already booked the tickets he apparently didn’t check the passport until he was at the airport and was denied the international flight because he didn’t have a current passport.

I never did get my money but I did get immense satisfaction that he didn’t get to go on vacation.”

Here’s what people had to say.

This person thinks they know how she should handle this.

Another individual thinks she should just let him wonder…

This Reddit user thinks she should go ahead and book the same trip.

And another Reddit user had a similar story to share…

A word to the wise to all the cheaters out there…

Don’t even try it!
