How do you know if a girl likes you for your looks and not your personality?

First u ask him whether he likes ur company or ur friendship?

If he replies he likes ur company then he is trying 2 flirt U

or if he says that u r his good friend then there are less chances 2 say that he only likes your look......it may also mean that he may even like u in total

it depends on U what kind of friend do u want 2 have him as
