What should i do with my friends?

ok so people say im pretty i have long legs a nice shape green eyes curly eyelashes and everything...whenever one of my overweight friends wears skimpy clothes no one says anything but if i even show half of my legs my friends always tell me i look like a whore and i should change i ignored them for a long time and whenever i went out alot of guys asked for my #...if this happens my friends say stuff like they did not get the guys # because they dont look easy and theyre basically implying tht im easy (FYI i dnt have sex) and alot of times a guy tht they like tries to approach me and they tell me not to be nieve becuz the guys r using me to get to them...i dnt hit on guys tht my friends likes and they kno this yet they still get mad. in order to avoid drama i stared to wear sweats and t-shirts whenever i was around them and they seem happy when i dress this way but i stopped becuz they became a little too arrogant nd tried to treat me like an ugly stepchild. im not conceited or mean and i dnt disrespect them the way they do to me. Im not afraid of them but i dnt wnt to approach them with my fists because theyre not the type of girls who want a fight. I just feel like theyre happy if i make myself less attractive. they really are great friends aside from this but i think i should drop them for awhile...is this normal?
