I'm confused about my relationship with a classmate
Hey, so I'm 21M introvert and I have no experience with dating at all. About 2 months ago I developed a crush on my university classmate (who is an introvert and Catholic). I decided to try to act immediately, so we've been on 3 one-on-one meetings outside of university so far. During the first one we walked for 40 minutes, then sat on a bench for another 40 minutes, and talked during both of these activities. On the second one we had coffee for an hour and then another walk for 1.5 hours. On the 3rd one we had some pastries for 40 minutes and then again walked for over 2 hours. This was 3 weeks ago.
I have learned so much about her and I am really into her, I mean we were constantly talking during those meetings. I know that she commutes for 3 hours every day just to get to classes, so she prefers to stay home when she doesn't need to go anywhere. She mostly spends her free time reading books, watching movies and tv shows, and playing computer games. We have also studied together twice for maybe a total of 4 hours and we have both helped each other with some things. During the 3rd meeting we made plans to go to movies together after exams (so around mid May) when our classes are over.
Around a week ago, I asked her if she'd like to go to the cinema this week, and told her I was free all Wednesday and Thursday afternoon. She wasn’t sure because of her thesis and an upcoming exam, and she felt like staying home to rest before her weekend trip. I said I understood and suggested we could try the following week.
Yesterday, I asked again if any day this week would work for the cinema. She said that she is unsure because she wanted to rest and she spend time with her sister who just finished her final school exams, and she might be able to meet for 3 hours on Thursday afternoon when she's visiting the city while her sister is at an appointment. Then she added that if the cinema doesn't work out, we could just meet up instead.
I feel like I made my interest in her clear by now. We are both introverts and there hasn't been any physical contact between us yet, I mean even the meetings weren't explicitly called "dates". So I feel like I have to do something now to not end up in the friendzone. I mean I paid for her, I said some things like how I really like spending time with her, I complimented her nails when she showed them to me on 2 separate occasions and even said that she herself is pretty (when I compliment her she usually thanks me while smiling in a quieter voice). But I don't think it's enough?
I'm completely unsure what to do when we meet again in 2 days. Despite her knowing about my intentions for a long time now she hasn't rejected me yet, she still wants to meet with me. Idk, should I tell her how I feel next time? I'm really lost.
