Most Helpful Guy
She's keeping you on the hook. If things don't end up right with the other guy, she's gonna go for you. That's why she pulls you back when you seem to distance yourself, but if you get close, she pushes you away. She's trying to keep a certain distance, not too close, not too far, so if she fails with the other guy, she can quickly go for you.
Be careful. She's playing you. You better distance yourself, and if she messages you, just ignore her, or act disinterested. Let her know she can't play you, or you're gonna end up bad.
