Marriage & Affair: Prisoner's Dilemma

Now you see, the Indian society is very conservative. Relationships (the lovey-dovey/just friends kinds) are always a contentious issue. But I think if one were to analyze the situation from the point of view of game theory, it makes sense to have an affair. Here's how:

As can be seen from above, the best payoff for either party is in case of them having an affair irrespective of what the other party does. So, why the counter-logical advise by the society?

Thappad se Darr Nahi Lagta Saab, Pyaar se Lagta Hai

I always thought that I wanted good people around me. I think I still want that. With that wish of mine, its sometimes comical that I get scared when someone is good to me. Without a background if someone is good to me I always get a little worried. In such cases, I have this weird feeling that there is something that the other person knows that I don't. And my mind is uneasy till it figures out the real purpose behind the goodness, the real event that triggered it. Typical examples are when someone is expecting something from you. There are many other such situations. I think the dialogue in Dabangg sums up the situation beautifully. Thappad se Darr Nahi Lagta Saab, Pyaar se Lagta Hai. That, is the paradox of goodness.
