<human>: Posting this on throwaway.  My SOs best friend (lets call er girlA 26f) is currently dating an absolute loser(21m). The kid is 21 and already has several felony charges(in fact hes in court right now for one!), girlA got chaged as an accessory in one instance.  He sells hard drugs(shes not a user), is verbally (observed) and physically (heard from SO) abusive. He cheats on her, they break up and reconcile constantly.  

The most recent time she went on a vacation with him and his family. They went out drinking,  the bf leaves "to go to the bathroom" goes back to the hotel and punches out a window getting the whole family kicked out of the hotel. Parents try to pay but their credit cards are declined so they ask GirlA to pay for the entire family's hotel stay and the broken window. She does it and then when she asks them to pay her back they bawk on ot and say that was never part of the deal.

Long story short the kids a scum bag from a scumbag family with scumbag tendancies and nothing my SO says to her can make her see the light. The drama is spilling over into my life and my home. 

Reddit, what can I do? I have several friends that would get in line to date this girl, she even shows some interest in a couple and my SO approves of the match up. How do I make this happen.

Can you condense the text into three sentences or less?
<bot>: SO's bff off and on a lying, cheating, stealing, soon to be convicted felon, is there a way I can convince her its a bad choice to get back together with him?
