I number closed a girl this weekend(Saturday) she was very into me and I already went ahead an set up a day/time for a date..

I texted her sunday night to invite her to a social gathering at a friends place( im in college, it was a party) she declined and said she had other plans..

Our date was getting close so I texxted her with the restaurant and time that we should meet up and she said she had made plans with a roommate to eat somewhere else; she invited me along or to re-schedule our date.

I didn't want her attention split by eating with one of her female roommates so I thanked her for the offer and said we'll meet another time.

Need advice on how to progress from here, I definitely do not want the girl to necessarily have the power in dictating where/when we meet and cancelling on plans that I suggested we do...Do I throw a "neg" her way or continue to allow her to be passive-aggressive in dates etc....

Thanks
