I see a disconnect... and there may be more than one possible explanation, but you need to find out the root...
It could be a mental-health issue - I don't have direct experience with that, just know its out there.
It could also be a relationship issue - insecure attachment, doesn't really trust anybody in his life, is looking to "take" what ever he can get, to try to "survive"... This one is serious, Attachment issues can start when they are very young - or, a child with fairly secure attachment can become detached, due to experiences... anything from abuse (that you may not know about... such as at daycare or school or a friends house), to major difficulties at school that are being labelled as "attitude" and "behavior" issues but really are not (there's lots of disorders and disabilities that are often missed)...
Its definitely a major problem.
Need to fight it on two frongs - take all steps possible to prevent it from happening, and then try to get to the bottom of it, because the only long-term solution is to get to the bottom of it all.
