I am looking for a twilight fanfiction story
so i read this twilight fan fiction a while ago and would really like to remember the name of it the story goes like this i think can't really remember it was a while ago. Edward and Bella where together until edward cheated with tanya at a party and later find out tanya is pregnant so edward decides to marry her and breaks up with bella so bella leaves. Few years down the line bella comes back and edward is married to tanya but tanya lost the baby edward starts to lose his mind in this story as he wants to be back with bella but feels like he is obligated to tanya because she is on drugs and am pretty sure edward kills tanya at the end i don't think this story was a long story if anyone can help i would appreciate it
