history: when someone tried to get me to go out to a bar behind my spouses back  A friend tried to get me to go out to a bar and hang out behind my spouses back...  Did you tell your spouse? I really think they should know.
current: I havent yet, but I agree with you I should. I just dont want them to be upset with my friends. 
next: Some would consider it cheating if you did not tell them.
