I haven't really been "friend-zoned" per se, but I have been "you are a creep that I would never date" zoned.
Granted after years of growing up and trying to better myself physically and mentally, I seem to actually be able to attract women's attention in a positive way as opposed to trying to just get in their pants.
The friend-zone is BS indeed. Just something guys invented to make it feel as if a greater force stops them from being in a relationship with the girl because they're such nice guys- the idea of the friend-zone. While she's in fact not interested in him at all, because he's either unattractive/a douche/incompatible or all of the above.
