Oh yah, i finally found the word for the feeling before - Apathy

It's means:
Lack of interest or concern, especially regarding matters of general importance or appeal; indifference.
Lack of emotion or feeling; impassiveness.

Funny... Listening to a audiobook - Men are from Mars and Women are from Venus. Dun noe why my bro downloaded it. But anyway, i'm listening it now. W00t~!
