hi guys so I (m14) have an older sister emma(19). I'm starting to get worried for her because I've heard her on the phone telling her friend about talking to this guy online. My sister and her friend call the guy "z". That's not the problem tho cuz she talks to a lot of guys and people in general online but it's the fact that I overheard her saying before that he was 30 and another time she told her friend she met him in a game when she was 13. it's gross when u do the math and idk why she would wanna talk to him when she was the one that caught me texting an older woman and yelled at me until i agreed to block her and never contact her again. It doesn't make sense.

My sister commutes to college in the next town over and I know she's already done a bunch of wild things since starting college. But now i'm starting to worry if she'll try to meet up with the guy after seeing a text message on her phone from "z" asking her where she lives in our state. I've tried asking her about him but she just tells me to stop worrying and mind my own business.

wibta if I told our parents about this? I kinda don't want to because my sister has never told our parents about the things that i've done and if I tell our mom, her and emma's relationship will probably just get worse. I could tell my other older sister about it but those two are also fighting at the moment. so idk what to do here and i'm just worried about her.
