I thought this story was very poignant. I'm giving you a link here. http://www.creativewritinglife.com/cwlshortstorycontest.htm
It's a competition I've just come across which is free to enter,ha a £100 prize and the theme is Regret. It could be perfect for this story.
Give it a try. Nothing to lose. Wendy
Thank you for your feed Back... I purposefully did not want to reveal untill the end the real cause of the separation as it builds anxiety amongst readers, however I see your point in atleast letting them know how she got herself into this situation, i.e: why did she lock the room in the first place, even if it were a casual reason i guess mentioning it clears a few thoughts. However I also liked the fact that because I hadn't stated why the door was locked, the reader pondered over whether it was a mistake or done on purpose... But I suppose one must let the reader catch on to something and not leave them to thier interpretation completely. Thank you for your pov ...working on this now..
