Dear Prudence,
I have recently found out one of my friends has been talking badly about my boyfriend behind my back. She’s been generally rude to him in all their encounters due to jealousy since he has come into the picture. But I keep giving her the benefit of the doubt because I know that she’s going through personal issues. This has been going on for months though, and finding out she is saying bad things about him to our mutual friends feels like the last straw. What do I do in this situation?
