Pregnant Friend Not Getting Married?

Hi I have a pregnant friend that is with a LOSER!! She had an affair with a married man and had gotten pregnant. He is now divorced and they live together. She never wants to listen to anyones advice. This is her first pregnancy and she acts like she will not be a good Mother. Here is an example. In her trailer park neighborhood, their is registered sex offenders. Her response was not even that worried. She said " Their is nothing to worry about."

Also,her boyfriend drinks and gets drunk around her. When she is due at any moment. I gave her advice that she needs to put her foot down. I told her this. Because, he needs to be sober enough to drive her to the hospital incase she goes into labor. She got mad at me for being concerned.

Also, I think her boyfriend listens to her conversations. He answers her cell phone. And he has used her phone to text me. And he has gotten into her facebook to send me a message. On top of that, he called me yesterday asking where she was at. I never met him in person, but feel weird of him.

He also will not marry her. Yet, he uses her car he has no car no good job. He is 25 and she is 39. Their is things he does. To where she acts different on phone if he is around. She has changed and acts like she will not be a good Mother. It has made me question my friendship with her. Partly because of her morals and acting like she wont be a good Mom. And acts so snoby. When we have known each other since 8th grade. Thoughts
