Has your BFF ever dated the guy/girl of your dreams but they did not know you like them.(THAT'S WHAT HAPPENED TO ME)

my best friend dated both of my ex's which I was for real cool with but he just recently broke up with her and she is like go talk to him, I'm just like no because him and I agreed to never talk again after we broke up and she don't respect that which annoys me.

Well could u give me some advice
