Is She Cheating? (English Edition)

Jack and Meg have been married 12 years and things are good... maybe not as passionate as they once were, but still, very good. Then one evening Jack goes into a bar and catches Meg flirting with a co-worker. In fact, he catches her doing more than flirting... And while he clearly could have stopped them, he doesn't. No, all Jack does is watch. Is Meg cheating? Well, she definitely crossed some lines. But what they both do next will decide if it really was cheating, or something else.
