My best friend likes my boyfriend 😅

I met my boyfriend four years ago and had this one sided love with him for almost three years. I met my best friend 2 years ago and she is the most sweetest person who I know. So about a year ago she told my boyfriend that I liked him and we started dating we broke up in the summer and we didn't talk for a while. I started talking to him again and this time as a friend he asked me out a week ago and told me to keep it as a secret for some time and I agreed. I was going out with my best friend today and she told me that she liked my boyfriend that she liked him and she asked me if we are just friends and u said yes. She asked me to set them up and now I don't know what to do .
