There is no definite definition on LOVE.
To me, it is a feeling you have on a person. Different feeling on
different people. Just like the love you have on your parents, on
your siblings, teachers, pets, etc...
If you have that feeling, you will treat them differently, like
showing concern, taking care of them, or do something to make them
happy, etc...
Love is different from relationship.
In relationship, it takes two or more pple to make it works but for
love, it is an action that has to be from you.
I think pple in this forum are having relationship problems rather
than love, XinYi.
