The Unending Poem

It's started with I
And follow by YOU
But as it continues
I can't find YOU.

The I is now gone
To where it goes
I don't know
I hope the You still follows
For where, destiny will knows.

A period is coming
To mark the ending
But I hope it's a coma
So there would be no ending.

But when a period is followed by a dot
and another dot
what does it mean?
Is it really the end
or an unsure ending...
