<human>: Provide a brief overview of the text.

I don't want to give a million examples, but my best friend is in an emotionally abusive relationship. This guy has cheated on her for the entire 2 years they've been together (but blames her for it), doesn't let her go out with her friends (because she's "meeting other guys", apparently), tells her what to wear, won't let her speak to any men at her workplace...I could go on, but he is abusive. She had an abortion last month because she thought he would end the relationship if she told him she was pregnant. She went through the whole process herself and he didn't care. 

It is killing me to see her like this. She used to be a happy and confident woman, but now...she's convinced she's worthless, ugly, has no future, etc etc. I fucking hate this guy for what he's done to her. They are apparently "on a break" right now, but she hopes they will get back together...even though he's dating some girl he met on Tinder. Seriously. I've tried my hardest to get through to her because he doesn't give a shit about anyone but himself. She KNOWS he is bad for her but she's been sucked so far in, she can't see any way out.

What can I do? I know I can't do much and I know that the realisation needs to come from her. I ask her to hang out every week, sometimes she turns the offer down because she "is sorting stuff out with her boyfriend" but sometimes she will go out with me and she'll comment on how much fun she had and how she wants to hang out more. I think she is slowly (very slowly) realising that she is worth so much more than this guy, but whenever she makes some progress, he pulls her back in. It is heartbreaking to see.
<bot>: friend is in an emotionally abusive relationship. When she starts to pull away from the guy, he pulls her back in. I want to support and help her but what more can I do?
