@Eliusa,
I didn't "let" her cheat on me. I obviously didn't know about it occurring.
Now you're resorting to getting personal because, why? You've lost the argument? Is that why? Do you finally realize that nobody is going to agree with your philosophy that cheating is okay?
I'm actually quite the opposite of angry. I'm with someone awesome now who is loyal, respectful, appreciative, etc. All the things that my ex was not.
"get a therapy"
the grammar of this statement speaks for the intelligence of the person making it.
