I’m sure you fiance loves this guy! FYI I was in this situation too, but as the guy bsf. Exact same thing. Ultimately I decided I do love her, but if I really actually loved her, the best thing to do was to let her go completely. I left her life without really saying why, and she was very hurt for a long time, but she will live a happier life this way and I love her enough that this makes me content.
My fiance and him are good friends but they became good friends bc of me so yea :/ but it's just hard bc I really do love my fiance like he holds a special place in my heart but me and my boy bsf have had on and off feelings for each other since sophomore year of hs and we're sophomores in college now... but it's just so hard bc I love my boy bsf and I feel I love more the idea of what could be but I don't think I love him in a way that I do with my fiance
