My friend is mad at me

Ok, one of my friends is bad at me (bobbi). It started during the weekend when my friend and I asked our other friend (sam) to go to the movies. She said she wouldnt go alone so I was like well thats no big deal I'll just ask bobbi if she wants to go. So I ask her and she gets all mad thinking im just trying to use her so I can go with sam. And now bobbi wont even talk to me, what should I do?

Umm your friends are really acting childish.. I think that you should talk to bobbi. That's it call her, leave her a message, anything. Tell her you were not using her and if that's what she thinks when I guess you guys aren't really friends.
Well good luck !
