My brothers skank *** girlfriend?

Life is life and although this sounds like it sucks I am thinking you will just push your brother away and if she is what you say he is going to need to trust you when he finds out for himself. if you try and confront him with all this info and no proof he could just reacte badly. I have been there with friends and fam and when someone is blinded by love they can't see and that's the bottom line. I would give skank girl enough rope to hang herself. keep your friends close and you enemies closer ya know.
