Here's my 2 cents. I don't believe a man and a woman can ever be BFF. Best friends forever. They can just be acquaintance normal friends or what we call "friend zone"

However, BFF that definitely doesn't exist. A very close friendship between a man and a woman will always have a small window of opportunity for them to be intimate and romantic eventually developing feelings for each other. The only possibility of that not happening is if they are not straight. Probably being gay or lesbian.
