I'm going to try to make this short so I hope it doesn't get confusing.
My brother lived with FI and I for about 4 years. About 8 months ago things got so bad between all of us that I let my brother know it was time for him to move out. My brother and best friend of about 6 years started dating about a year ago. The other day she called me crying. She said she didn't want to start any trouble but she felt like she had to tell me about some things my brother had said to her. I guess they had gotten into an argument about FI and I and my brother had said something about killing FI. She was extremely upset by it. She said that the way he said it and the anger he had when speaking about us concerned her. I don't know if I should tell My FI. Part of me thinks yes. That FI should know to watch his back around my brother. The other part of me knows my brother. He is a trouble maker. He wants to get a reaction from my FI or me. He wants us to seem like the unstable ones. What do you all think? Should I tell FI?
