Angie, you don't need your ex bothering you about your work schedule. Put him in his place. File a Restraining Order. Just go to your police station. They will advise you. Just say the truth. How you think he may hurt you. How he looks at you in a menacing manner. You feel threatened by him. Keep it general and nothing that can be disproven, i.e., he punched me in the face. The restraining order is almost automatic and will ruin his life. He will be consumed by it and will leave you alone.
