I've read a few articles recently that seem to be citing scientific research to show that love lasts about 2 years. Some of them say that romantic love then gives way to companionship or some other kind of love....but mainly, the evidence seems to be concluding that love declines over time - and significantly around 2 - 4 years. Can anyone restore my faith in long term relationships or would it be better to aim for a series of 2 year love affairs?
