As for me, i would like to understand it the simplest way it can be. Love is a form of expression through actions. It comes right from the heart which is then express through actions. Human likes to complicate things by defining things with formulas, profound terminologies when its just straight to the point and easy. Agree?
Having said that, i still having problems loving. I realise love is very subjective and many people feels differently about it. Loving your way may not be a form of love to the other party when they think otherwise. For instance, i know my gf don't like me to be worried. But i still am because i am worried for her safety and her well-being. However, she feels vexed because she can't do anything about me worrying. So, i'm caught in a dilemma.
Giving another example... My gf feels that she should not text me when i am busy because she may disrupt my work process. This is a form of love! But i decipher it the other way because i was hoping that she can text me and tell me she is worried about me and that she missed me dearly or at least post something sweet on my fb wall so that i feel warm and fuzzy. You see the point i am trying to deliver.
Even until now, i am still trying to understand. :(
