Its good to hear that the idiot finally stopped harassing you. Who knows, maybe this is just a little scam he has going. Whatever it is its definitely nothing against you personally.
When I was 17 or 18 I was backing out of a friends driveway and backed into a car I didn't see. His driveway had a huge evergreen tree at the end that caused a blind spot. It was a woman and the accident made her spill coffee all over herself. I found it odd that there was no indication that she tried to swerve out of the way or even lock up the brakes. She didn't blow the horn either. I didn't even realize I hit somebody until after I looked behind me. I thought the bump I felt was just my back end dropping off the edge of the driveway. It was like she swerved into me as I only pulled out a few inches to hit her.
I was a new driver and this was a new experience for me so I didn't question it too much. A cop came and ended up not giving either of us an infraction or anything. No big deal I thought and never heard another thing about it. I didn't even get my truck fixed as it wasn't in the best of shape anyway from all the off-roading I did plus only the bumper got beat up a small amount.
A year or so later I get served with papers that she was suing me claiming the accident caused her all of these various medical conditions and loss in quality of life.

Needless to say I was very upset by it. I had to get a lawyer and have a deposition. Thats when I realized how full of crap she was. Her recollection of events included that I was driving a white Jeep but I drove a black 86 S-10 pickup. Come to find out she was a scam artist from Florida who would place her car behind people as they were backing up so that she could sue them to get money.

The ridiculous part is I ended up still having to give her settlement money for whatever stupid reason but thankfully it wasn't a lot.
