So last night I was chilling at a frat with my friends and one of my girl friend walks in with two girls and 3 guys. The guys are all AFCs and not really a threat so I knew I could spit game on my friend's hot roomate. So they enter and my friend's roomate says she's gonna leave cuz she's tired or some shit. I'm sitting right by the door and as she turns around to leave I go:

Me: You're gonna leave and you haven't met me yet? That's not right.
Her: Oh well I'm Kate, what;s your name.
Me: I'm Brett but you're just gonna leave your roomate here with these guys? That's not very nice of you
Her: I'm the one walking home by myself. You should be worried about me.
Me: Well do you have a rape whistle (our school gives them to freshman girls)
Her: No but no one's gonna rape me. Look at these guns (flexes her muscles)
Me: You're probably right. Who would want to rape you?
Her: *laughs*

Then she says goodbye to her roomate and when she walks out she touches me on the shoulder and goes "Bye Brett".

Anyway, cut to today. I'm talking to my friends about last night and I bring her up and find out that she has a bf. I feel like I got off to a pretty good start with her (at least for a beginner) and I have confidence that I can hook up with her but I definitely need help with this. Apparently she's really devoted to her bf but I figure it's only a matter of time before she gets lonely. Any suggestions as to what I need to do next? I feel like I definitely need to kino and DHV to build attraction but I can't believe that's all I need to do. Maybe you guys can see something in this that I don't.
