So I've seen this girl keeping her head down when we exit the class with smile on her face realizing I'm looking at her. Her class is after mine. This happened multiple times. Once I was talking to other chick, she saw the chick first and then looked at me and I kept the gaze on her and she touched her hair while going in the study room. Now I've seen her at our food court talking to other girl while touching her hair continuously when I was exactly 90 degrees at around 10 feet. I'm sure her peripheral vision recognized me. I'd like to add I'm one of the attractive guys at our school.

I approach her 1 week from then, she was friendly, nervous, talkative and said 'you're smarter than me'. And I wanted to get her number she got a call, and kept talking for good 10-15 minutes. Then made another call once first one ended. We board the college bus and when the stop comes, she gets down and we go our own way without saying bye.

4 days later, my class gets over, she is waiting outside class with few people even though their class is 15 minutes from our class end time. Took some balls, I approach, ask how she is , how was her weekend and then tell her I wanna check this restaurant, does she wanna join? She says 'something has happened back at home' I'm not sure' I say what's her number, she looks at my phone and visibly nervous and shaking, I ask why is she so nervous. She says she needs to go now to take care of something and she will see me later. I didn't get the number of course but was disappointed. She is visibly shy person as one could make out.

2 days later, I'm in same study room as her, siting very close to my female group mate (pretty close concentrating on laptop) and she noticed me when she was walking out.

How should I take it from here? Thank you!
