I once had a crazy boyfriend who threatened me and I had to move away (2 states) before I felt safe. He not only stalked me but one night ran out in front of my car and I was so startled I slammed on the brakes and he jumped in my car before I knew what was going on. It was terrifying. I had him locked up for 3 months after that (he couldn't make bail and I had all the threats he sent me in letters [before the internet]) but for years, YEARS, he told people who knew me that if he found me he would kill me. I didn't come back for 20 years.
