Is this backstabbing?

Jessie sounds like a trouble maker. People like her that try to cause problems are usually insecure. They figure if they tell one friend something bad that another friend said about them, then that friend will be so grateful to her. It's kinda like diverting the attention away from her. I hate people like that. It's just shady how she ran and told her stuff that wasn't true, and then asked her not to tell you she told her. Childish I say.
