If the girl has that one audio clip you can guarantee she has plenty of others, and possibly even video to go along with it. Quite likely, due to it being an abusive relationship on his behalf, he'll have left her a string of violent and threatening text messages which will act as lovely evidence against him, and who knows what the police will find on the home's security cameras. At this point you'd imagine he's rather screwed, but he's an incredibly rich and privileged lad and has the money and fame to fight it. Very sad that United knew all about this and stuck with him regardless.
