Together again

He was her everything.
She was his everything.
He loved her.
She loved him.

When he cheated on her with her bestfriend, everything fell apart.

She couldn't sleep, or eat.
He didn't call to check on her.

He truly loved her, but didn't know what to do after what he did.

She forgot about him.
He didn't forget about her.

She tried to avoid him.
He couldn't avoid her.

She would see him and hold her head up high, not letting what he did to her affect her.
He would see her and want her, want to talk to her. He knew she wouldn't. So he just gave up.

What happens when they are forced together again?
