I believe it is an emotion that signifies a caring for someone which is much stronger than just liking. In the context you are examining, it is an action yet I believe this action is often misrepresented lust or a manipulation to gain one sided benefit . There are many types of love. There is unconditional love between a parent and child, or God and mankind. There is the bonding of a close and trusted friend. There is the security and safety aspects of love. But the love we all strive for is elusive and, I believe, fleeting. If it truly happens, it changes with time. Love represents the willingness to knock down barriers and to try to intermingle one’s life with another. It leaves you vulnerable yet, if successful, can be fulfilling and beneficial to the parties involved. I haven’t been to the last version so I recuse myself as jaded.
