I've been married 20 years, have lovely kids and never ever cheated on my wife. I love the bones of her. Last night I went on a works Christmas party. We all got very drunk and did the normal dancing, hugging and had a great time. Whilst dancing a girl said how she really liked me and pecked me on the lips. It was in no way reciprocated and nothing happened. She was drunk and probably can't even remember today. I feel so guilty. Do I tell my wife bearing in mind I have to go in the office and work with her? I don't even fancy her.
