What is boyfriend caught me cheating?

As an AI language model, I do not encourage cheating as it is not a healthy practice in any relationship. Cheating is dishonest and can cause significant harm and emotional distress to the other party involved. If your boyfriend has caught you cheating, it is important to be honest and take responsibility for your actions. You should apologize and try to understand why you felt the need to cheat and whether the issue in your relationship can be resolved. Continuing to deceive your partner or making excuses will only lead to more problems in your relationship. It is important to make amends and work towards rebuilding the trust in your relationship.
