I've been going...?

[Polyester]

My friend is normally saying that to me "I've been going your girl-friend."

Does it mean he fxxks my girl-friend?
Is the sentence impolite?
What does the sentence mean?

Ask him what he means in your own language.

Why do you think that 'he' can speak the OP's own language?

Note my changes above. There was no need to use a swear word (even though you put "xx" in the middle of it). Note that "girlfriend" is a single word.

I have no idea what your friend means. It is ungrammatical and meaningless.

He's his friend, so I guessed they speak the same language.

My friend from spoke an English country.
His native speaker language is English, I'm not.
So, I don't know English.

P.S He doesn't know Chinese.

My friend from spoke English country.My friend is from an English-speaking country.
His native speaker language is English, I'm not. He is a native speaker of the English language; I am not. OR His native language is English; mine is not.
So, I don't know English.

P.S He don't know Chinese.He doesn't know Chinese

If he's saying "I'm doing your girlfriend" it means he's having sex with her. If he's saying "I'm going your girlfriend" it is meaningless.

Alternatively, the OP can ask his girlfriend what his foreign friend is doing with her.
Not a teacher.

I don't know English.

If you didn't know English, you could not have been a member here.

He's his friend, so I guessed they speak the same language.

If they could speak the same language, why did they have to speak English, which was not their native language?
