A similar thing happened 5 years ago. I was working out of town in Orangeville, and went to a club in Brampton with my sister and friends on the friday night. She knew a girl who was friends with my sister, so she sat at our table. I felt sorry for her because she was on a blind date and was stood up. Danced a few songs with her, and all of a sudden she acted like we had been together for some time.
She invited me back to her place north of Orangeville to spend the weekend. I told her I lived in Muskoka, and had to get home. Then she wanted to come with me. I told her I was going to be on the road quite abit, and didn't have time to spend with her. I finally gave in and spent the rest of friday night with her, in her bed at her request. We got as far as her givinng me a BJ and me going down on her. I had to get some sleep, so I called it quits only to be woken up twice with her trying to ride me like a cowgirl. After the second attemp, I got dressed and left.
She pulled a fast one on my sister, telling her that she had some tiles in the tub that needed fixing and got my # from my sister. She called me telling me she was going to the doc for birth control pills, and she wanted to see me again.
Then the harassment started. She found out where the bar was, that I was doing a tile job in and started bugging me at work. Then she found out my home #, then where I lived. Tracked me down one weekend at my property in Muskoka. Moved twice in one year to get away from her, changed towns even, but she still tracked me down. Offered herself to me, to do with as I pleased on my birthday.
Finally shook her in 2000, but not soon enough to avoid several trips to the police, lawyer, and extra expenses in moving as well as purchasing a couple of different vehicles to use to hide my whereabouts from her. I finally figured out how she was tracking me. I drove a unique 4x4, and she keep driving around asking people if they had seen it, til she found out where I was.
