The cornerstone of a sustainable relationship is true love. And true love is beyond poetry, romance, or gifts. The bedrock of true love is the perpetual pursuit of the well-being of your partner. It doesn't grow randomly. We have to cultivate it and nourish it to flourish.

The sustainability of a couple is a huge investment of resources. Bargaining is an essential skill that helps lovers to always negotiate and compromise. A lover will invest humility and empathy to conclude a deal for the union's sake. Being in love with someone is a full-time job. You need to act as a good diplomate. Indeed, bargaining helps prevent crises.
