>>22679676Dude, if you're dating a nerdy girl that cosplays and she's into you, she'll find a way to #1 fuck you, #2 introduce you to her nerdy shit and #3 introduce her nerdy shit into your sex-life.
My brown exgirlfriend loved Avatar and loved to cosplay as Katara, specially when she convinced me to go as Zuko with her. She introduced her ZukoKatara shipping fanfics into our sex-life and I've never been happier.
She probably just saw you as an innofensive guy to hang out with, what they call an "amoeba friend".
