Back and forth...

I did promise to submit some of my work, so here's a short story I'm particularly fond of... It's a first draft, so all critique is welcome...

Back and forth he paced. Back and forth. Stopping each time only to check the clock.
3:13.
Always 3:13. He knew it was broken, had been for weeks, but it was a habit and somehow felt comforting. A little tiny oasis of normality in a maelstrom of emotional upheaval. It didn't last.

'Yes, I'll buy the batteries. If you would only remember on your way home to check your phone it would've been ticking by now, though.'
'Thanks. And remember to enjoy yourself, okay? It's been a while since you last went out for lunch.'
'You're so patronising sometimes, why do I put up with you?'
'Somebody has to. You're just lucky, I guess'
'Oh, go away!'
'I love you too'

That was the last conversation he'd had with her. The last thing they had spoken about was batteries! He kept replaying it over in his head; at least he'd remembered to say he loved her.
He glanced up. 3:13 again.
'Well, one thing is certain, it's not 3:13.' He announced to the empty room.
He checked his pocket. Another habit; he knew his phone was now in pieces, embedded in their new tv. How long had it been since he heard the news? An hour? Half an hour? Five minutes? He had no way to be sure.

'Breaking news from Sunderland: The Lambton Worm today became the latest in a series of arson attacks on pubs in and around the city centre. Emergency services are currently at the scene, but the fire still rages on. It is unknown as of yet how many survivors there are, but an estimated 70 people were in the building at the time. We now go live to...'

Everything after that became a blur. He remembered trying to call her, but getting an answerphone. Not surprising, she drained her battery most days playing candy crush. He tried again, and again, and after the fifth time he lost it; threw the phone at the wall and missed, effectively cutting off all communication with the world.
He'd considered going out, but they'd only just moved here. Where would he go? Who could he see? It had all seemed so perfect this morning and now everything was chaos.
3:13.
He wanted to scream, to hit something, to charge off. But instead, all he did was pace. Back and forth. Back and forth.

Okay, I know it's shite, but I can't yet find the original which was much better, when I do I shall edit this to include that, combine the two and maybe finally have a story, but for now what are your thoughts?
