So my brother's life has pretty much been dismantled thanks to my step-mother. My brother's high school diploma has been set back greatly because she didn't want him to move back in. My father did nothing to change that and allowed her to walk allover him and my brother. Thanks to this my brother was cut off from his highschool, unable to finish his classes.

This was prior to moving to another state so it got even more complicated to get him back on track, until recently. Thanks to our step-father and his mother, my brother has a shot to get what he needs to get back on track (Our step-father is a great man btw, I'm going to get him something nice for Christmas to show my appreciation. Not sure what his mother would be interested in though).

So that is one part of his life we can fix, the other issue is with women of his age. I feel he is vulnerable currently and shouldn't be mingling with other females. He has no job and no diploma, so his earning potential and resources are zilch yet he allows other females into his room (yeah this is juicy gossip). Now I'm not saying my brother is stupid, but as well all know here, most women are dangerous. I don't want him to get screwed over so what should I say or do to keep him on the right path before it is too late?
