Weird situation

My boyfriend has a friend. He’s single and has taken multiple girls on dates. He’s told my boyfriend that he’s jealous of his relationship with me. He’s told my boyfriend that he wants to find a girl like me. My boyfriend recently went out with him on a date I was supposed to go along but I didn’t want to go because of COVID. My boyfriend met this girl and said she looks like me and that it freaks him out. I don’t know how to feel about this. Anyone have any idea what this could be about. I have no interest in my boyfriends friend.
