Applying Game Theory into Relationship

Are you being emotionally blackmailed by your partner? What should you do? Well, according to this article, based on a reasonable payoff matrix, all you have to do is to make it clear to your partner that your payoff at “Make up & Apologize” is less than the payoff at “Break-up”. However, do not abuse it! Or you may change the underlying assumption about the payoff matrix and end up regretting.

Here's another excuse to break it off with a partner:

If you have strong ties to your friends and a strong tie to your partner, but your friends only have weak ties to your partner, you have a bunch of unstable (+,-,+) triangles in your network. To make these stable, you must break up. A stable network has two opposing camps each with has strong ties withing and only weak ties between the camps. You and your friends become one camp, your partner becomes the other.
