The OP hasn't expanded much at all on the opening post.No she hasn't so its all rather academic

It is most likely wrong no matter what the circumstances are due to the boys age.  agreed

How did they meet? ( not good if she was in a position of authority - teacher etc) That would be very wrong and criminal IMO

How long have they been dating? are they even dating?

Do his parents know? who knows it could be a wind up

If they do know, do they care?  There are some that wouldn't

As asked previously - what does dating mean in this case (going to the movies once a week?) and do they spend time alone, if so doing what?  yes what does that mean in todays english
