My girlfriend needs to speak the language that I do.
What is wrong with the way that your girlfriend speaks English?
It doesn't sound natural to me. It sounds like a robot.
You should encourage your girlfriend to continue practicing English instead of asking her to speak your native language. If you keep encouraging her to practice English, she will improve in time.
Bitch doesn't listen to me. I'm going to tell her off and explain why she needs to improve her English.
You should not talk about your girlfriend like that. If you want someone who speaks your language then you need to find a new girlfriend.
