I am pretty sure being cheated on is one of the most hurtful things that a person can do to their partner. It not only destroys the relationship completely or to the point where you know it’s never going to be the same, but also leaves quite a scar on the partner. So while some couples try to reconcile and move on from it, others don’t even consider it.
For example, this Reddit user chose the 2nd option. He shared online that after he found out about his wife’s affair with her CEO, he got both of them fired and left her without any discussion.
