For any of you who've been following my posts, you'd know I'm currently going through break up.

After much hassling/begging from my best friend to go out to a bar with her, her bf and some friends, I finally decided to give in.. what will an hour or 2 hurt right? Well, I feel like a shitty ass friend and now I'm conflicted.

So we start the night at her house, get dressed and head over to the bar. We are all at the bar area waiting to get our drinks and all of a sudden its just me and my best friend ( her bf went one way and the other another way) shortly after her bf comes and starts raising his voice at her asking where his friends are, at this point I'm confused (is he raising his voice cause he can't hear from the loud music or is he screaming at her?) I asked her if everything was alright and she said yeah, he storms off.

Fast forward 10 minutes pass and he's back screaming louder and now I can kinda interpret what he's saying "I'm gonna fuck you up" at this moment a bunch of people are starring at them, she's just being quite, trying to calm him down... I finally pull her away and ask her what that was about and she says "He's mad at me because I don't know where his friends are" WTF ?!?!?!?!

She's crying hysterically and she tells me he pinched her and now I'm angry but I'm genuinely afraid if I confront him, she'll turn on me too. I get my phone and call and uber, take her out of the bar and we go home. This whole time she's crying texting him, and I'm so confused... I tell her "honey he's abusive and you didn't do anything wrong, he is crazy. Leave him alone. this time he pinched you, next he'll shove you and after that he'll smack you and the what ?" to this she replies " it doesnt matter now he left me, he broke up with me", I tell her "that's what you are concerned with? GOOD he's doing you a favor"

I don't know what to do.. I kinda want to speak to her mom and tell her what's going on but I feel that is not my place and I don't want to lose our friendship but I feel I need to do something. I also don't want to be a bad friend but I don't know if I can or even want to be around this kind of thing.

THIS is why I don't like to go out in the first place,ESPECIALLY with people my age. The whole thing was just immature and super embarrassing and abusive, Like what is wrong with this guy ? My bf and I have major issues but I've always felt safe with him, He's never raised his voice at me nor been aggressive. This was so shocking to me, I have never seen anything like this except in movies.

I don't know how to go about this, what do I do?

TL;DR

- finally went out after my break up

- my best friend and her boyfriend get into an argument

- he raises his voice and verbally abuses her in front of everyone in a bar

- I called and uber and got her/us out of there

- I don't know what to do or how to help her
