So my sister meet her best friends 3 years ago. they were best friends. Her friend was my best friend to we were all sisters. But this summer she got a boyfriend and completely changed. She always said I don’t want to lose my virginity tell after high school and stuff about how she wouldn’t no matter what. Well she did with the guy that’s very verbally abusive. she’s in high school and doesn’t deserve that. But she completely changed. well my sister started not hanging out with her and doing her own thing. then. they stopped talking. I miss her so much and always think about her. I stay up and cry about her all the time. I so badly want to say goodbye to the old her because i never got to even say goodbye because she wasn’t my main friend she was my sisters. It’s been bothering me so much lately and i don’t know what to do.
