How do you feel about the 'friendship zone'?

Never really been ina friendship zone, but i do have girls tht are friends tht i wuldnt date bc they're too much of friends. I dated a few frienss b4 which didnt rlly work out that well... But yeah. I think that i shouldnt date girls that are friends, there a reason ther're not a girlfriend or boyfriend..bc were all just friends. But i usually date people i get to know for a month or two and hang out with a little and flirt and things so were not yet like goood friends but start to like each other so therefore not awkward bc there not in the zone but still are a friendish person you are fimiliar with and know well enough to decide if you like them or not
