What do you say?

What do you say? What do you say to someone who just doesn't seem to get it? To someone who is being manipulated and used? To someone who deserves better but refuses to see that she does?

I don't know what to do anymore.
This person has always been used by people. Low self confidence if you ask me. I'm no Dr. Phil, but I'm not stupid either. Her last relationship was with a crackhead. She lived with him and his crack addicted friend, and didn't find out until later (and after living with him for over 2 months) that her own boyfriend is an addict. They abused her emotionally and used her for money, rides, food, and God knows what else. She finally leaves. Only to meet another boyfriend through an Internet dating sight. She meets him after only talking to him a couple of times. Declares her love for him. I think she is so desperate for someone to love her, that she looks past obvious faults and warning signs. In less than 2 weeks she moves in with him and his mother in a trailer park. He buys her a dog. He's been to jail many times, has 2 kids, and the mother of these kids lives with his dad in another trailer. He doesn't drive because he's lost his license to many times for DUI. He's stole her car one night with some girl, and then brought it back, stripped of it's high-end stereo and speakers. Her bank account was drained and her credit card has a balance no one is sure of. He says he'll pay for things, and then makes her pay. She's almost lost her job because she is with him, or driving him to work. She wants to be super skinny like the kids mom, so she's starving herself. She sits at my kitchen table and finally cries. She says she's done with him, but does want her stuff back. I say cut your losses and move on. Focus on you for awhile. You don't need trash like him. She cries saying it's over.
He calls.
She leaves. Says every person deserves a second chance. Gets mad that we argue otherwise. He's a loser and sees easy prey. She's with him now.
What do I say to make her realize she deserves better? To expect and demand to be treated well, or you don't need the jerk. Love yourself first.
What do I say to her to make her see?
Is there anything to say?
