This is a great story, serves her right. However, I'm kind of sad that they had to drag her mother into it. She sounded really excited for her daughter's birthday.
However, I know that it will definitely help in the divorce with her mother having first-hand knowledge of the cheating. It was a great plan!
Best part, her family will still like you and hate her since they saw it with their own eyes. None defending her saying "my sister is not a cheater, he's probably the one." ... of course... now it's a meme and worldwide that you knew beforehand. But still brilliant.
No, no, no. It was completely unfair to drag all her friends and family into your imploding marriage. There was no reason to hurt her family because you are mad at her. That's petty and mean. Get your evidence, ruin her birthday, etc but don't hurt her family.

"How could you?"
How could you have sex with another man in the bed you share with your husband?
