my best friend of 10+ years has suddenly been acting weird with me. we are very close but at times she acts very different (in a bad way). she has made comments about my body, called me flat and all these times she laughs it off as if it's a joke and i do too because i don't want to seem "sensitive". today she did it again and i lost my cool for a bit. another thing that's been bothering me is that we are a group of 3 friends and the 3rd girl we have friends with since the past 3-4 years. now what my bsf does is whenever the 3 of us are having a conversation, she just grabs the 3rd friend and leaves. initially if run after them and catch up but i just stand alone and stay that way most of the time in school. sometimes i have my boyfriend with me but he has different classes so i am alone most of the time. but the thing is I don't know why she's becoming so weird. i feel like crying
