What am I to do...?

Holding on... remaining who I am... a wanderer who isn't looking for another half...~
Letting go... moving on... finding someone to complete me...~

I realized that I was holding on to something that didn't exist anymore.
That the person I missed didn't exist anymore.
People change...
The things we like and dislike change.
And we could wish all day long that they didn't.
But they always will...~
Am I holding on to something I need to let go of...?
How do I know whether it's the time to continue holding on or time to let it go?

Time...? Do I need more time, wait for a little while or should I act now...?
