UPDATE: My (23 f) best friend?s (23 f) boyfriend (25 m) is so jealous he wants to ruin our girl?s night out.

I posted about this situation last week and I thought I?d give an update on what happened last weekend.
Here?s the original post.
Angela put her foot down and told Derek that she didn?t want him coming along with us on our girl?s night out. Derek gave her an ultimatum that either he came along with us or they were through.
I had a talk with Angela on Saturday morning and she told me about the ultimatum and said she was tired of Derek thinking he could run her life. So she and I want and had our nails done on Saturday afternoon with the gift cards that my boyfriend Rob had bought for us. If you didn?t read my original post Rob is Angie?s brother. He said he sometimes feels like he stole his sister?s best friend so he bought us the gift cards so we?d be able to spend some quality time together.
Saturday evening Angela, me and three of our other girlfriends went out to dinner together. During dinner Derek was blowing up Angela?s phone with texts. She tried to ignore them but eventually she responded that she was still going out with us and that was that.
We all went to a club and had some drinks and danced until around midnight. Our friend Jenny was our designated driver and she dropped us off at our places. She was going to drop me at Rob?s house last. We went to drop Angela off at her apartment and Derek was waiting in the parking lot.
He started screaming at Angela and at us. Saying that we were encouraging her to be unfaithful to him. We were all pretty scared and I wouldn?t let Angie out of the car. So Jenny took me and Angie over to Rob?s house.
Rob had some of his friends over Saturday night for a game night. When we got there his friend Tony was still there. Rob was really ****** when he heard how Derek had acted. Him and Tony took Angela back to her place. I guess they had some words with Derek and he ended up leaving her place.
Rob insisted that Angie should stay that night at his house with us. He was worried that Derek might come back. So now Angel has told Derek that he needs to leave her alone or she?s going to call the police. He tried to apologize for how he acted but Angela told him they are through.
So far Derek has left her alone aside from saying he needs to come to her place to get some of his stuff. Which she agreed to as long as Rob and her dad are there when he comes.
I know Angela feels bad that her relationship didn?t work out but I think she?s better off without a guy like that in her life.
TL;DR: My (23 f) best friend?s (23 f) boyfriend (25 m) gave her an ultimatum about going out with her friends. She went anyway and he got aggressive with her about it. She dumped him because of it.
