<human>: Give me the gist of the text in a nutshell

so i met this girl through her sister. she gave me the girls number after asking her if it was okay if she gave me her number.

so i text her, everything is nice. we have a lot to talk about and so i asked her to go see a movie, not as a date just to hang out and watch a movie. she said okay and that was it. we talk some more but we are planning on going sunday and she hasn't responded to any of my texts? (i sent one text asking her if she wanted to meet me there or if i could pick her up.) and that was about a day ago. shes been on facebook and twitter since then from mobile (not snooping. we follow each other on those websites) every time i sign on she signs off.. should i take this as a sign she isn't interested? 

i'm thinking on waiting till sunday and texting her again asking her if she still was planning on seeing it with me or not. if she isn't interested i'd prefer her to tell me instead of pussy-footing around it...
<bot>: asked a girl to the movies, she agrees everything is going great. now she is ignoring me.. should i assume its nothing is going to happen or should i wait and text her on the day we planned?
