So I'm in uni and have been playing games and such with a group of friends off and on for a while.

This girl in the group keeps on trying to prod me by asking personal questions and interrupting the group conversation and attempting to get me in private situations. 
She also doesn't respond to typical "I'm not interested" hints/body language.

The Thing is I really want to get to know another girl in the group better but can't with the first girl trying so hard.

I'm afraid that by shutting down girl #1 I'll lose my connection to girl #2 and I wont be able to get to know her better.
I've even tried asking for her to stop asking me questions and things like that but she still presses on.

What do I do in order to politely tell girl #1 that I'm not interested while still maintaining the group dynamic in order to get to know girl #2 better.
