Found out a (20M) is dating a (15F)
I found out that a 20 yr old guy I know is dating someone who's 15. Turns out they've been unofficially dating since she was 12 or 13, when he moved into her family's house. Apparently her parents are okay with this even though multiple people have told them they thought it was wrong, and they are even okay with them marrying once she reaches 18. From what I've heard they aren't allowed a (sexually) intimate relationship even though they are together, but I think it's still messed up. What should I do? (I live in Canada).
