so my boyfriend thinks I'm 'fat'. and he is obviously into thin and underweight girls and oftenly 'jokes' about how I'm fat. it just makes me feel a little sad and insecure about my own body which is rare and very sad for me. i even started getting thoughts of joining the gym.
but other than that, he's a guy full of green flags
how should i tell him that I don't like it when he 'jokes' about that?
