Block him and be done with it. He is holding you emotionally hostage and you owe him nothing. I had a guy text me a pic of his revolver a few weeks ago. He wouldn't respond to me asking if he was ok for over 2 days. In those few days I didn't sleep and had horrible nightmares. I sent him one last goodbye text and blocked him everywhere. Knowing him, he probably thinks I'll come back at some point.
