I'm talking to this girl. Both in highschool. It's talking not dating but we both have a thing for each other.

She talks to my friend AS friends. I know she wouldn't fuck him because he is probably the most beta man I know. Good guy, but horrible at talking to women. Anyways, her talking to him makes my friend think that she likes him. He's the type of guy who is like "SHE WALKED BY ME AND TOUCHED MY ARM I THINK I'M IN THE PUSSY" type of guy.

Should I tell her to not talk to any of my friends. And make that clear? Or would that make me seem sensitive? What would you suggest? Thank you.
