Hey guys, So my friend is 14 years old and she is in a relationship with a person who is turning 18 soon. She has matured a lot, but I still know that this isn't a healthy relationship. They aren't just in a relationship as in they say they're dating but the furthest they've going to kissing. I know they have sex before. Both people are friends of mine and I don't want the 17 year old to turn 18 and be put on the sex offenders list, for something like this. Any advise on how to deal with this? Should I leave it as is? Or should I tip off someone?
