You knew he was an asshole. Think about that. I am sure he hurt you in a horrible way but now you will free yourself from him. Very sorry you are hurt. I send you hugs. When the pain begins to subside, do some thinking about how you let yourself get so attached to someone you would describe as an asshole. You deserve better than that. Let this be a learning moment. We can't help who we find attractive, but we can choose who we let into our lives and heart.
