My friend recently moved from Russia to America a little over a year ago. We met in school and have been friends ever since. Back in Russia she told me how she always dated older men, drank, smoked. She has also been through a lot in life. Like the death of her biological parents and the death of her adoptive father. Awhile ago I introduced her to my family friend (15) and they really hit it off. They ended up dating. All was well until my family friends 23 year old friend who i also know started messaging my Russian friend on Facebook. (She is sixteen) He wanted to meet her in person and wanted to have sex with her. Somehow my family friend found out and now they aren’t talking. Eventually my Russian friend and the 23 year old stopped talking. My family friend told my dad what was going on yesterday and now my dad wants to get involved. He told the 23 year olds father and now he might go to jail, if he decides to call the cops. I also found out that nude pictures were exchanged and that the 23 year old is a drug dealer. My dad wants to know all I know but I don’t want him to tell me I can’t hangout with her, she is still my friend. I am not sure what to do. My family friend and Russian friend broke up because of it. Any advice?
