What is love?

Does love just die off by itself after a couple is together for a long period of time? I really wonder... I do...

Come to think of how Kenny had been cold and distant from me for the past dew weeks ... I do feel very very down.

I know he is busy at work but he will still talk to me and all before. But recently he had went all quiet and refused to share anything in his head. The best thing is that I can see his gears in his head moving and tried to get him to talk but he will always insist that there is nothing.

He gets moody more often and then he refuses to talk.
