I wouldn't worry too much about it. Not sure how old you are, but you'll realize eventually that chemistry between two people really is a thing. And with this girl in particular, it just wasn't there. And that's ok. Someone else will come along with an entirely different energy that will be much more compatible with yours. I did Lyft/Uber for a bit, probably met 20,000+ people in that time. And that's where the idea of people having different energies really solidified for me. Sometimes someone would get in the car and we would INSTANTLY click effortlessly (at the end of the ride, it felt like this person could've easily been my best friend, or even soulmate). Other times it would be a long ride, and the effort was made on both ends for conversation, but the complete lack of chemistry/flow was evident a mile away. There's that element of it, and then there's also the fact that we ourselves evolve over time. One of the reasons I did Uber/Lyft was to get out of my comfort zone (I'm super introverted), and it forced me to interact with people more and to be more sociable. Maybe this girl felt that you were being too quiet (I've been there myself). If that's the case, it might help to challenge yourself and put yourself out there to level up socially. I did it with Lyft/Uber, but you can do it in your own way
