Unfortunately I have had run-ins with my ex. He ended up being sort of crazy. He would follow me around. When I would leave my office I would see him waiting in his truck a block down the road. He even would sometimes follow me almost all the way home.
One morning I got a call from him (didn't think he knew where I lived). He told me to look outside and when I did, there he was sitting in my driveway.
Oh, and this I could never prove he did, but I have not doubts in my mind that he did. I came into the office one day and there was a note on the top of my computer saying, "Look at your candle and tell me what you see". When I went over to a pillar candle that I had on my bookshelf it had been chopped up with a knife. Then I noticed that there were wax shavings by the window as if the person who did it was watching out the window to make sure no one came. The police came but couldn't find anything to connect him to it. He must have made a copy of my key while we were together because the office wasn't broken in to...
Okay, I'm scaring myself all over again just posting this. Luckily I am now happily married and have left that town. I'm pretty sure I will never run in to him again......
