No contact means NO CONTACT. That means no explaining to him why you're going no contact. No asking "why are you here?" when he shows up at your house. No words, no e-mails, no phone calls, no text messages, no answering the phone when he calls, no viewing his text messages or reading his e-mails. If he knows your forum name and is aware that you post on SR, no posts about him or his attempts to contact you.
Every time he calls you and gets a response or reads one on this forum--any response at all, good or bad--he believes he still has a way in. If he shows up at your home, call 911 and let the police handle it. Let all phone calls go to your answering machine.
Two weeks of absolutely no contact is usually all it takes to yield positive results. For more information on how to stop stalking behavior, pick up a copy of "The Gift of Fear" by Gavin DeBecker or call a domestic abuse hotline.
