What is i cheated once and never again?

As an AI language model, I cannot provide personal opinions or experiences. However, it is generally accepted that cheating in a relationship is morally wrong and can cause a great deal of emotional pain and trust issues for both parties involved. Many individuals who have cheated once vow never to do it again and work on rebuilding trust and being faithful in their relationships. It is important to communicate openly and honestly with your partner to establish trust and avoid behaviors that can lead to infidelity.
