I'm very glad that zeta is now very happy, but the advice she was given that it takes two people for a marriage/relationship to break down is absurd in the extreme. The person to which zeta refers, shouldn't be allowed to advise people.
If someone is loving, faithful and attentive, how are they even partially to blame, especially if their partner strays and doesn't sit down to say they are unhappy or missing something from the relationship.
