<human>: This guy apparently had so much potential. He went to Oxford, graduated with flying colors... And never got a job. He lives at parent's home at 28 and makes about zero pounds per month in income. He spends his days getting drunk and playing video games in literally the basement of his mom's house.

Now that's none of my business. It's his life, their family and what they do with him is their business. I don't give a shit. Except when there's an expectation to treat him as if he's such a great guy. Everytime you see him he's talking about how amazing his time at Oxford was and how it changed him as a person (turned him from a promising and intelligent kid into a adult full time drunk gamer). I don't have anything against gamers, I do it too, a couple of hours a week. Not 8 hours a day.

The thing is that this mentality exists in all their family. My girlfriend constantly tells me how smart her brother is and how proud she is of him. I mean, yeah, I'd be proud too if my brother went to Oxford, when he was 21. I wouldn't be proud if he didn't do anything with his life 7 years after he graduated. So I said this to her one time, and she said I'm being disrespectful and petty and I'm jealous. That I'm judging without knowing him and I should apologize.

This is insanity. I don't know what to do. I wouldn't have cared if he just did what he wanted and nobody was trying to sell the idea that he's such a success but when everyone in their family talks about him, it's frustrating. If he was the fucking prime minister I would have understood. But he's a nobody with a prestigious piece of paper in his hands.

Not sure if I'm just venting or there's any advice you can give me about how to handle my girlfriend and those situation where I'm gonna be interacting with that guy or with other people when they talk about him.

Can you give me a shortened version of the text?
<bot>: Girlfriend's brother is a complete loser and everyone treats him and talks about him as if he's so amazing. They expect me to do that too but I can't.
