I really liked this, though noted what has been said and I do agree you could flush this out a bit more. Usually while reading I get very distinct images in my mind of the characters but here I saw the white dress and the tux but no faces. There is something much more powerful about truly seeing the characters in the mind.
Aside from that I thought it was very well done. There were twists which is not always easy for something so short... like I did not see the video coming, nor the prostitution, nor the affair. It kept me interested and that is good.
Here is where you may not like me very much
I apologize in advance but the end seemed like a cop out to me. It is hard to believe someone willing to subject themselves to prostitution and pornography would throw it all away because of a ruined wedding. People that are suicidal tend to have those thoughts throughout their entire lives yet she has shown no indication of being anything but a fighter. Fighters do not give up.
To me, I see her finding Roger and giving the prick a taste of his own medicine, and then seeking out Dylan and making him listen. Like the way she fought for her education (which she still has by the way) and fought out of her home (which she is still away from).
Anyhow this is just one opinion but I think you could do so much more with this, you have an incredible foundation!
