"I can't be in this relationship anymore. It's all I think about and it rips me apart 24 hours of the day. I'm sorry, but I'm leaving you."
"You don't mean that."
"It's over."
"You don't mean that."
"Goodbye."
I screamed. I screamed as humans shouldn't. I clawed at my chest and ripped my hair and screamed as I watched the door shut behind him.
I woke up in a cold sweat, panting and moaning the word "no".
I just don't have the energy to cry.
