Abusive boyfriend

Em

So my bestie has been dating this guy for a little over the year. He is about 10 years older than she she is. He doesn’t drive ( court fees), he lives in her home for free. Ok he is abusive toward my friend. The fight all the time. He has to know her location at all times He treats her like shit when she gives him everything. Like I love my friend. I want to see her happy. I know she isn’t happy with this guy. What do I do? I realize that every one has there breaking point but she needs to leave. She isn’t getting that is in an abuse relationship. I don’t what to come off as an asshole.
