How to help my friend???

Rebecca • Living life on the edge

Hi girls!

A friend of mine has an ex boyfriend but she still loves him. Apparently he might be on drugs. She wants to help get him out if it. His friends seem to be controlling him and he has changed for the bad.

The reason why they broke off their relationship was because his father didn't want then to be together so she broke it off.

How can I help her bring him out of this problem???
