SUBREDDIT: r/relationships
TITLE: Any tips how I [19/M] can explain to a girl at my barn [14/F] that dating a [23/M] is a bad idea
POST: Basically my main point so far has been how there is a huge difference in mental maturity but she doesn't buy it, I'm pretty sure she deals with slightly severe self-esteem issues so the guy probably threw a few compliments her way and now she's falling for him completely. I don't wanna go behind her back and contact parents because that'd probably kill any trust she had in me and cause really high tensions at the barn, plus if they arrest the guy I won't be too comfortable with the knowledge I just fucked over some random dudes life completely. Idk if this would be the right subreddit for this sort of thing.
TL;DR: 
14 year old fell for a 23 year old, want to tell her it's a bad idea but she's not budging and I don't wanna have parents contacted and punish her and the guy.
