What if I could move on?

I'm listening to the All American Rejects song titled 'Move Along'. I listen to it over and over again, just to persuade myself to move one. I regret that my heart is still with him. I regret that I'm still with him. Maybe not in a special r/ship like before, but still... I regret that I'm crying right now because I feel worthless and like he never cared. If I never mattered to him and why he is still here? So, what if I could move on?

"Go ahead as you waste your days with thinking
When you fall everyone stands
Another day and you've had your fill of sinking
With the life held in your
Hands are shaking cold
These hands are meant to hold

Speak to me, when all you got to keep is strong
Move along, move along like I know you do
And even when your hope is gone
Move along, move along just to make it through
Move along
Move along

So a day when you've lost yourself completely
Could be a night when your life ends
Such a heart that will lead you to deceiving
All the pain held in your
Hands are shaking cold
Your hands are mine to hold

Speak to me, when all you got to keep is strong
Move along, move along like I know you do
And even when your hope is gone
Move along, move along just to make it through
Move along

When everything is wrong we move along
(Go on, go on, go on, go on)
When everything is wrong, we move along
Along, along, along

When all you got to keep is strong
Move along, move along like I know you do
And even when your hope is gone
Move along, move along just to make it through"
