Confused By My Pendulum

A few months ago, I had a nightmare that I would lose my husband in the near future. Because I have had dreams in the past that ended up true, I went out and bought a pendulum.

After the pendulum confirmed my fears, I asked it a series of questions such as, "Can I prevent his death?"
"When will it be?" etc.

But, the day had come and gone and he is thankfully still with me.

While I was working with the pendulum, I asked it a series of other questions to test the accuracy of it, and out of 32 questions 23 were correct. I know that record is not very impressive, but it had me going all this time.

What I don't get is why I went through all this anxiety alone for many months if it wasn't true?

Should I just get rid of this pendulum if it only feeds my fears and anxiety?
