Friend-zoning would require of the other person to suffer. If one person wants to be a couple, and the other one doesn't, the only option is to say goodbye. Anything else is emotional abuse and exploitation.

I can say that I never attempted to friend-zone anyone, but, the very idea appalled girls and women and they did everything they could not to be in that position - they knew this means they will have to witness how another woman takes the role of a lover which would kill them of jealousy and suffering. And, surprise - men are as human as women are. Friend-zoning men is just as inhumane, and demanding them to accept it (or, manipulating other men to demand it on behalf of women) is pure cruelty and selfishness.
