Offering (native English, British) looking to learn Brasilian Portuguese with a native

I know a lot of the basics but there’s a good amount of gaps I’m missing and would appreciate to try and fill those in, my girlfriend is Brasilian but we mainly communicate in English, I’d like to be able to improve my Portuguese so I can have actual conversations.
