People love dating

Unrequited love refers to those feelings of love that are not reciprocated.

It is a much more potent sentiment than a simple liking for a person.

Recent studies in neuroscience have indicated that as people fall in love, the brain consistently releases a certain set of chemicals, including the neurotransmitter hormones, dopamine, norepinephrine, and serotonin, the same compounds released by amphetamine, stimulating the brain's pleasure center and leading to side effects such as increased heart rate, loss of appetite and sleep, and an intense feeling of excitement.

Research has indicated that this stage generally lasts from one and a half to three years.

Most commonly, love refers to a feeling of strong attraction and personal attachment.
