He can't handle not being there for her.
She knows he can't always be there to save her from her demons.
He thinks he is her one and only but in reality, he isn't the only one wanting her.
She knows she needs to choose but she can't one is sweet and is her best friend and the other is her boyfriend and everyone knows that they like each other but people ask if they are friends with benefits. She knows if she breaks her boyfriend then her best friend will be scared that she will break him.  She wants to choose her boyfriend but her best friend is a sweet temptation. Her boyfriend acts like he wants her but never actually spends time with her.

Two halves make a whole
Two hearts join to become one soul
Two eyes that see one truth
We see different skies but take comfort in the same moon
We promised to never leave the other alone, that the love would not be gone too soon
Rejoicing in the moments from heaven,
Comforting each other when hell breaks loose.
Together through each others mountains and rivers.

Forbidden lust, forbidden love
Two souls that are forced apart
Two that yearn the others heart
Accepting each others flaws
One boy that’s far away from home,
One girl that’s questioning her own

But half a heart is better than none cause it can always be completed by the chosen one, But half a heart is like half a sun
Would it still be as bright as the full one?
Would the love be the same knowing that the other is not as strong
Why must these two hearts fight what’s in their souls
This burning desire
This passion they hold
Why must they put the flame out and become cold
Why waste away the hearts of others when they know the real future is with each other
Why not combine their hearts to become whole, to become one soul.

But having half of anything is like having half of nothing at all
It’s settling for half the love
Yet it could be more
Having half of love must be impossible, must be wrong
-The world is only existent because of wholes
One half cannot love for both
One half cannot fathom growth.
So why not have two halves of a heart
Two broken souls
Let the shattered remains of the other halves be the glue that makes these two people’s love whole
Because why face the world as half a person
When facing it as a whole is already near to the impossible

Two halves of a heart make a whole
Two hearts join to become one soul
But these two halves will never join
These two people will face the world alone- together, but lonely, like two sides of a coin
Not knowing the existence of humanity is dependent on whether they choose to love each other or choose to let it go.
The existence of humanity is dependent on all our lost souls.
