It is widely accepted that cheating on someone, especially someone you were in a long-term relationship with, is one of the worst things you could do. And vice-versa, being cheated on is one of the worst feelings in the world. That moment you find out, beyond a shadow of a doubt, that they've been straying, it's very natural to feel rage.
What definitely isn't normal or acceptable is inflicting any kind of physical harm on your partner in order to punish them for cheating. Two wrongs certainly do not make a right.
But incidents like these occur on a daily basis, and they are very much, examples of domestic violence, regardless of whether or not they were motivated by an affair.
Watch the video below to learn more about domestic violence against men and the effect it has on their lives...
Forty-four-year-old Rachel Biscoe was so enraged after catching her fiancé half-naked on the phone with his lover, that she reacted in the most violent way imaginable.
So what did she do? Well, it's so gross that it really doesn't bear thinking about, but it did happen and Biscoe even confessed to the crime.
Biscoe sliced open the scrotum of her former fiancé, Trevor Camp, with her diamond engagement ring and what's more, she even managed to avoid jail.
