My friend always makes comments on my body in front of other people. Even if we’re in a big group, she’s like “we should put (me) in our bags because she’s so skinny and short.” I’m not even short but I’m skinny and she knows I don’t like it. She doesn’t do this to our other friends, and it’s always embarrassing. She even did it in front of her boyfriend last time (made a comment about my body out of the blue) and he told her to apologise but she never did. What should I do?
