Yeah, she'll really go for you if you turn into a big stupid macho player.
You sound young, so I'll say this gently: relationships actually ARE founded on communication. If you're interested in more than just a scam, you should be straight with her about how you feel. OPEN with how confused and insecure and frustrated you are. Let her get into your head a little bit. Girls think it's sweet when you tell them how messed up you are over them. Then tell her what you want with her, and how you don't care about any other guys, or whatever happened.
