<human>: Can you provide a brief rundown of the text in within 3 sentences?

I asked a girl out for dinner last Friday. She's the prettiest girl i've seen and we are having the same calculus class.
I haven't dated girls in months and haven't ever gotten into any relationship before, plus English is not my first language and my entire social circle speaks Mandarin. So I got super nervous before picking her up and during the date. She didn't talk much during the dinner and refused to go to a movie after the dinner because of an unfinished assignment that was due on that night.
After walking her to the door of her dorm building, I asked if I can call her later (yeah i guess that was super dumb) and to my surprise she said sure without hesitation.
Then one weekend later she's not picking up my calls and not responding to my messages. So i guess that "sure" was just being polite.
<bot>: I'm a university student but there is few girls in my program. English is my second language and I got nervous when the girl doesn't talk much, then the nervousness kinda ruins the date. Any tips?
