i don't think you should waste your time and try to save her. it's not like it's her first pregnancy and if she didn't learn the first time, she won't the second...or third. personally, i would really distance myself from her. life is had enough without having an extreme fuck up for a friend. i know it sounds harsh, but people are mainly responsible for their own lives. all you can do is offer support, but don't spend too much time with a person like that.
