Please do keep in mind that getting back to you isn't an invitation for you to send a million texts while this person is also trying to have a life, a job, friends, etc. That just gets weird.
She'll take public transportation to hang out with you
If you notice that you're in her neighborhood for every date, it can mean she's not that invested in the relationship. Someone who likes you will take any means necessary to get to you: bus, subway, Uber, rickshaw... And you ought to be returning the favor.
She never asks to reschedule
If a woman changes the time, location, or day of your rendezvous, she doesn't see you as a top priority. This does not fare well for your chances of winning her over. It means she would rather stay at home, isn't willing to put in the effort to see you, or something better came along.
It's OK if she reschedules on you once. Hey, life happens. But if she does it multiple times, she's not that into you and you should move on.
