“The “amount” of love one experiences depends on the absolute strength of these three components; the “type” of love one experiences depends on their strengths relative to each other. Different stages and types of love can be explained as different combinations of these three elements; for example, the relative emphasis of each component changes over time as an adult romantic relationship develops. A relationship based on a single element is less likely to survive than one based on two or three elements.” - × × ×
