If these two dopes would just say what’s on their minds…but no, it’s much more melodramatic to have them be unable to express their feelings like adults.
The ship of narrative has lost its rudder. TB spends two years setting up the Les/Cayla thing before allowing them to consummate their relationship, only to have them agree to “take a break” a few weeks later. Props to Cayla for finally showing some backbone; negative props for following that up with an internal “one more chance”.

Les blocks out his wife’s apparition long enough to fuck another chick who, self esteem issues aside, is attractive and available, and the moment she says “I love you” he recoils in horror.
