I was talking to this girl over the semester, got her digits and everything was cool. We texted like every 2-4 days and she seemed interested, and in-person she was super-comfortable with me hanging one-on-one and being playful and touchy-feely. I haven't talked to her since last week, and now she isn't responding to my texts. I texted her yesterday, no response. She responded to one today and I texted back with no response. That was 2 hours ago. Should I give up on her? Or should I be patient?
