Craziest person you ever dated? Not met but dated.

I went out with a girl I knew for a while from college. She was actually an amazing person. The first few dates we went on, she told me about how she wants me to meet her grandma and how her grandma pretty much raised her. It was a very touching story. She went on to tell me how she won't date me if her grandma doesn't like me, of course she was joking, but she said how much her grandma's opinion means to her. Well, one day she picked me up to finally meet her "grandma". She had a basket lunch and a cooler with drinks in it, so I figured we were going on a picnic. Nope, we went to the ST. Thomas cemetery! Her grandma had been dead for four YEARS! It is not a made up story lol It was really hard for me to kind of blow her off after that, because I felt like a horrible person. I didn't end it solely because of the grandma situation but it was clear she had issues with losing someone that she deeply loved and obviously meant the world to her. At that time of in my life, I just didn't wanna deal with it.
