Time.

Is there any man left on earth who is able to love you the way he first did, do the tiniest little thing for you with his very own initiative like before, treat you as wonderful as he first did or before...

and etc etc etc. It goes on.

I highly doubt so. Everything would basically change overtime.

Is it just human nature or something?

Why can't he be as sensitive as before? Why can't this? Why can't that?

It goes on..

I'll be thrilled to meet any who aren't like that, if there's any.
