I went through something like this after moving to a new town:

Saw an old acquaintance (we worked out of the same office when I was in college, and she also was a friend of some distant friends of mine) at a community event. First time in about 15 years that we've seen each other, and the first words out ofher mouth are about whether I'm married yet. We promise to catch up, and a few weeks later, I followed up with her by calling. Her behavior had been weird but I remembered my friends' ties to her, so I thought, "Why not?" We agree to meet for drinks the following Friday evening.

She picked me up, and we headed to a small eatery away from our workplaces. During the course of the conversation, she does everything from forbid the discussion of my former girlfriends to steer the conversation to a hypothetical relationship situation. She would get testy, with no warning, and I began to look for harmless topics of discussion and to let her know I'd need to be getting back to my car soon.

She says fine but wants to show me a "really cool house nearby that everyone new to town should see..." So, I warily get back into her vehicle and proceed to the street with the house. We get out, and look at the house. "Well, OK, I really have to get going..."

"Wait!" she says. "There's something else you have to see, further up the road!"

This woman drives me up the street, we round a corner and are atop a hill with a view of the city.

I look around and see pairs of people seated here and there, all cozy-like.

This nutjob has brought me to the Point, Make-Out Mountain, Lovers Lane.

In a panic, I walk all over the hill going, "Oh, that's the direction of my home! Oh, that's the direction of where I work. Welp! We've seen it all! Thanks!"

To this day, she acts as if I mistook her behavior for romantic interest. And, I do my best to stay far away from her.
