As everybody here has said, it isn't PTSD, it's abuse and I'm so sorry you're going through this :( I went through the exact same and it wasn't until a hospital stay and the police telling me he would kill me that I managed to convince myself enough was enough.
My ex used to also say he'd kill himself if I left... It's just another way of controlling you. Please stay safe xx
