During the early phases of a relationship, our brains are stimulated to send pleasurable neurotransmitters around our bodies. They eventually rebalance after 12–18 months. This stage is referred to as “passionate love.” Following this comes “companionate love,” which is less intense, but is more stable. It affects the parts of your brain associated with long-term bonding, and so grows stronger over time. The most dangerous point in any relationship is the transition from passionate to companionate love, as what was once exciting and new transforms into something seemingly ordinary, and perhaps a little dull.
Some end the relationship before it gets to this stage, maintaining shorter relationships to stay in the passionate love phase. However, while trying to repeat the great feelings associated with passionate love can be tempting, this doesn’t bring true fulfillment. Settling down offers us the chance to complete ourselves, and find the deeper love and connection that only comes with a committed relationship.
