OP says that his girlfriend “doesn’t even know how to basic sh—t like post a f—king letter” and after she got her first car, she didn’t want to learn how to care for it, and it had a severe breakdown because there was no oil in it. But the actual problem was this:

"We booked a holiday for 2 weeks to tour South East Asia. I asked her if her passport had at least a year on it. She said yes. At the airport she found out it was expired after I had a look at it. I asked why she hadn’t checked to renew it: her dad was the one who had sent the application in 10 years ago and she didn’t know it had to be sent in to be renewed (wtf?)."

The OP was furious, so he boarded the plane without his careless girlfriend:

"I returned from the holiday (she didn’t answer any of my calls or text whilst I was abroad) and once I was back she chewed me out for abandoning her at the airport (its a 20 min train ride from our city center and the terminus is at the airport), that I should have double checked her documentation since I know about this sort of stuff. I told her, sorry, but I ain’t pissing 3000 pounds up the wall because you didn’t bother to check the exact thing I asked you to. It’s really frustrating because I don’t want to treat a partner like a child, like my dad did with my mum.

AITA here?"

This basically seems like a “validation post,” or one where you are convinced you did the right thing, but you want approval from people on the internet.

The OP and this girl have been together for two years, and he is aware of what’s she’s like. Most people seem to agree he was nonetheless right, and she’s wrong for being angry:

There is a significant percentage of people that say “ESH” (Everyone Sucks Here) and ask OP why he is staying with his girlfriend.

But the most significant  comment comes from throwntheheckaway1, who writes, “NTA but you’re also probably not compatible.”

If the OP wants to be an adult, he should break up with this girl, so she could find someone willing to take care of her, and he can find someone more independent.
