Stalkers... Ick. Have had two ex-boyfriends stalk me after their respective breakups. They both had the same first name and were born in the same state- which is kinda weird.
When I was a kid my single mom was being stalked by an unknown person. He (presumably a he) left hang up calls and breathers, left pornographic pics nailed into our tree and taped all over the house. Took pictures of us as a family at places like the zoo and at movies and sent them to us anonymously. Even took pics of my brother and I on the school playground and sent them to my Mom... It was pretty bad.
I'm glad you are documenting everything. It is such a pain and so unfair to have to work so hard, but it is necessary. A few women I know who have been stalked felt more secure and more in control after they took self defense lessons, if that is any interest to you.
Hang in there.
