PEOPLE!! Can i have the truth on this matter please?

When you ask a girl out and she says ' I really like you "as a friend" ' or ' I just dont want a boyfriend or anything like that at the moment ' or when you kiss her spontaniously and she stops it and says ' This probably isnt a good idea, we are such good friends '. Is this all just code ped down from generations of women to get rid of the guy and simultaneously make him feel bad for seeing her in a different light and trying to be her boyfriend. Surely being good friends is a good grounding for a relationship but never seems to be for me. I think its coz im a bit fat, why dont they just say ' NO i dont fancy you, im way too good for you, my Brad Pitt is gonna be coming for me soon and you can stay in the background and watch with heartache""Friend""! ' and just admit that they are just as, if not even more SHALLOW than men!! Just say it and stop confusing poor guys who like you and maybe they will then do something about it, instead of being upset and confused thinking they did something wrong!!!!! Im crushed and have no confidence with women anymore after so many rejections.
