<human>: Summarize the given text in a few sentences.

My friend Kiara has been dating Harry for about five months. Our group of friends (myself included) did not like him from the beginning. He was very cocky, self absorbed, and frankly often made sexist comments. He's also an angry drunk and has gotten into multiple fights with random guys at bars for looking at him/Kiara the wrong way. He's a total asshole. 

Things have only gotten worse. He's starting to exhibit signs of domestic abuse. He is incredibly controlling and blows up her phone whenever she's out of sight. He never lets her spend the night without him. He's come and picked her up from places when she's been hanging out with us and not checking her phone messages. 

He spends a LOT of money on her, and often uses that as leverage to get what he wants. He's mean to her family. He's mean to us. He's a complete psychotic jerk but he's so sweet to her when he want's to be and her emotions are being completely manipulated. 

We've tried to talk to her in many ways, as a group and individually. She gets incredibly defensive whenever anyone mentions anything negative about him, often citing that we never liked him from the beginning so we're biased, and that he's great all the time when they're alone and we just haven't seen it. 

Has anyone else been in the same situation? I just don't know what to do. I am genuinely scared when he's around, and I see less and less of her every week. She's slowly slipping away from us and I don't know how to stop it.
<bot>: My friends boyfriend is controlling, manipulative, and abusive. He's terrible for her and none of us like him, but she will not listen to us when we try to talk to her about it. How can we help her?
