One word comes to mind, moron. With that reasoning I'll go tell my wife it's OK if I get drunk and hook up one time with a neighbor because it's just 'life'. Think she'll go for it?
Once your in a serious relationship and consider it exclusive, any physical activity like that involving someone outside the relationship, drunk or not, can be considered cheating. If he wants an excuse to fool around with someone else you know how to give him his freedom to do. Yes, talk to him. Did I get his middle name right? lol
