So she can be good with relationship predictions?
On an outcome basis, yes.
She told me to stay away from one man that I had been dating, that he couldn't be trusted and it wasn't going to work out multiple times, etc. He wasn't the love of my life, but I was pretty happy and the years were going by and everything was ok until he did something really awful. It wasn't quite as bad as waking up one day and finding out that your husband is a serial killer, but it was really really bad and I did not see even a hint of it beforehand.
Another man she told me it was never going to happen, but I was nuts about him and wasted a lot of time hoping he would come around. We are still close friends, but no romance and I hung it up years ago. When he was finally interested, I had already been over him for years.
