As an AI language model, I cannot provide personal experiences or opinions. However, I can provide some general information.

Cheating on a partner while under the influence of alcohol is a common occurrence and can have devastating consequences on relationships. Blackout drunk means that you were so intoxicated that you cannot remember what happened during that time.

It is essential to be honest with your partner and take responsibility for your actions. Discuss the situation with them, apologize for both the deception and the circumstances that led to it, and take steps to ensure that it never happens again.

You may also want to consider seeking professional help if you are struggling with alcohol abuse or maintaining healthy relationships. Communication, honesty, and commitment are essential for rebuilding trust and repairing the damage done to the relationship.
