I have changed my phone number. I've changed my email. I have blocked any ability for him to contact me. But he knows where I live. I have never gone all out no contact like this, so I know that will disturb him. I know he will show up at my work or my house. How do I handle that? Do I look like through him and blandly ask, "Can I help you?" - as if I don't know him. Do I slam the door in his face without a word? Do I act all friendly and then let the hammer down? Do I act sweet and then say, "Get out of here immediately or I will call the police." Any suggestions?
