Yes, this happened to me twice.First, it started in campus, this bff of mine turned against me and took away my boyfriend. She'll always pretend to be good to me and whenever we had issues with my boyfriend, he would help me in solving them.I later on came to find out that she's been spying on me and investigating the people am hanging out with then would go tell my boyfriend. It didn't last longer and my boyfriend dumped me.This is one hell of a betrayal I'll never forget in my life.
Then there's this friend of mine we used to share secrets.We actually shared everything including our family secrets.Later on after we had a misunderstanding, she turned against me.Instead of abusing me with my characters or what I possess, she abused me with my those things had told her about my family. This broke my heart and I cried bitterly. Since then I learnt a lesson, I'll never tell anyone about my family and issues that we're having, let them find out themselves how my family is like.
