translate this into english

Whats the meaning of this translation? I smell something bad about this. Here's the phrase, ''Datte mama bakkari nanda mon'' and also, ''Betuni okotte naiyo''.

Thanks in advance.

Dindo,

We would definitely need the context for the first one (at least).
"Datte mama bakkari nanda mon'': something like "....Because, it's only for mom" "...Because you only do things for mom" etc., but again, I could be completely wrong. Please provide the context.
'Betuni okotte naiyo'' ...sounds like "I'm not upset at all" "I have no reason to be upset/angry."

thanks AK for your immediate response.
i just started to learn japanese.

Here's the context.
I was just apologizing to my japanese girlfriend through text message that i am going out to meet my friends that night. the scenario dont include my mom. i guess "mama" means "so so"

That's "ma-ma-"
mama is mom.

So if its like this, ''Datte ma-ma bakkari nanda mon'', is she talking bad at me? because of the word bakkari?

And if she says, ''Betuni okotte naiyo'', so therefore she really is upset??? shes just pretending?

It really can be pretending to be upset or really be upset... you 'd have to ask her. But from the tone of the sentence you can say she's upset.
