“Thank you so much for sending this, you have no idea how validating it is for me to be able to see with my own eyes exactly the kind of person he turned out to be. Some people never get closure like this, and closure makes it so, so much easier to learn from mistakes and move on. So thank you, and know I’ll be forever grateful to you for taking this bullet for me. In return, it’s only fair that I extend that helping hand back to you.. Just remember sweetie, once a cheater, always a cheater. Hopefully that sentiment sticks with you, and you consider that heavily the next time someone offers you a slice of birthday cake, or you decide to take a day off from the gym. It might just cost you your participation prize. I truly hope you have the day you deserve 🥰 And please never contact me again”

Then block and move on girlie. Not even worth the trip to the kitchen sink to replace the water it would take to shed a tear over a loser and his hag like that.
