Avenged Sevenfold - Afterlife

Marco opens the connecting door; to Bella's room.
Bella sees him.
Bella runs to him and hugs him.
It looks like, they haven't meet for a long time,
though they live together in the same apartment.
Marco stares at Bella, strokes her hair and says, "How are you?"
"I'm... Good", says Bella and she touches Jacob's cheeks.
She miss him.
He miss her.
They kiss, like a lover.
He kisses her hard, like he never touched her before.
Bella looks... Clumsy.
But she's trying her best.
They kiss, for 15 minutes.

"Bella...", Marco stops the kiss and strokes Bella's hair.
"She needs me. I have to go"
"Do you need her?", asks Bella, and Marco hugs her.
"We'll meet soon", and Marco leaves her, alone in her room.

They have been living together for 2 years.
Marco lives next to Bella's room.
They even have connecting door.
So it makes them easy, to seeing each other.
In love, yes.
But Marco has someone else.
Diane is Marco's fiance.
Surely, it hurts, for Bella.
But Marco convinced her to not to cry or hurt.
He told her that he loves her very much.
But... Things change.

Then, Bella realizes something.
She cannot have Marco.
Marco belongs to someone else.
She needs Marco beside her.
Marco needs her, but he needs her fiance too.
What should Bella do?
Bella still sitting on her bed and cry.
