My girlfriend is arab all of her friends are speaking arabic she have a huge circle friends mix woman/man they are all drinking alcohol despite being muslim.

So long story short I'm the only guy who doesn't understand or speak arabic when I'm her group i felt like shit everytime they start to speak their language and all of them are laughing. They will only speak english when they want to ask question or when they feel like I'm out of place so me just sipping my drinks and smile when my gf look at me trying to act everything is fine but tbh i don't know how to handle my self how not to look bored or awkward cuz i can't understand what they are talking.
