i need help with a girl situation

[ebepse]

so recently this girl ive had a crush on broke up with her bf. how long do i wait until i make my move? and fwiw i dont really know her too well i guess, just through some internet forum. but shes hottt imo. except she tilts her head in every picture of her. maybe im just crazy, but perhaps theres more to this than just a silly pose...
