Hi all. Here is the story. I got this ring last year as a gift from someone who I wanted to beleive was my friend. She wasn't and deep down inside I knew this, but had the stupidity to overlook all the signs. So here it is. I am positive the ring was given to me with bad intentions. What do I do with it? I still have it in my house. And I don't want it here. only I don't really know how to get rid of it. Please help with and advise. Thank you all, your answers are greatly appreciated.
