<human>: One of my best friends from elementary has this jerk boyfriend, who won't stop abusing her (mentally and physically). They "fake" fight (ex: punching, slapping, pinching) all the time in class, in the car, etc. Some of the teachers and students have commented on how rude the boyfriend is and how their "fake" fighting isn't fake at all.

I talked to my friend about it and she said that she wants to break up with her boyfriend, but her mom won't let her. Her mother is dead set on her daughter and this guy to be together, forever. 

The boyfriend is telling me to take birth control to get bigger boobs and how hot that would be if I did, right in front of his girlfriend. I get really awkward and try to shut it down before it goes to far.

Can you condense the text into a few key points?
<bot>: My best friend is being abused by her boyfriend and wants to break it off but can't because of her mom. How do I help her escape?
