So I’ve been friends with this girl (I am 19 she is 17) for 3 years. We’ve became bestfriends within the past 2 years. Well she was dating my fiancé’s bestfriend (20) for almost 3 years and he broke up with her for another girl in October or November. Since he has broken up with her she has been with 3-5guys (just in November- February) she got pregnant in December but she didn’t know who’s it was because she was with 2 guys during her fertile window. She had a miscarriage in January. Now she is with another guy and she’s supposedly drunk and is posting on her Snapchat story a picture of the guy and the picture said “the best dick I’ve ever had i swear he had my legs shaken”. In the 3 years I’ve known her she’s never been like this. She’s giving her self a bad name. She’s a senior in high school and i know how other high schoolers are and i don’t want her to set that name for her self and get picked on. Do y’all have any advice on how i could talk to her and help her out? I really don’t want to see her do this to her self. She’s my best friend.
