Over the weekend, my brother's girlfriend was shot by her ex-boyfriend, who later died of a heart attack from a drug overdose of PCP. I can't help but feel sorry for her, but at the same time, I'm concerned for my brother. This girl has a shady past and some shady people that she associates with. Since my brother has been dating her, he's blown off all his friends and doesn't keep his commitments. I'm afraid that he's being led down a destructive path and I don't know what to do. Any suggestions?
