True love is not an emotion- we all have emotions which could be a means of expression of love but is not love.
This is easy to see when you think about the fact that love is long lasting and emotions that can come and quickly go.
The truth is that love brings forth many rich and varied emotions including emotions called feelings loved, lovable and loving which may be why people, confuse love with emotions. But feelings are fleeting. Emotions are constantly in motion, so they cannot be the valid basis for determining love.
