Valid Love - Main guy's wife starts cheating on him with this guy she meets. They start dating, but if I remember correctly they never go farther than kiss. Honestly can't remember even if they kiss. Also, in the end, her "love" for the other guy felt more like pity because he was a loner and she felt bad for him. She also used the other guy as an outlet because she married the main guy right out of highschool and never had an adult life outside of being married.
