Stuck in Monotony

kinda unrelated but this might be part of my issue, any advice is appreciated. i was hanging out with this one chick i met on an app and we went on a couple informal dates just hanging out and a lot of it was me listening to her talk. she said i was easy to talk to. we hung out and drank and smoked a bit but it never ended up leading anywhere, which was weird because she literally showed me her vibrators and “accidentally” showed me pictures of her tits on her phone but whenever i tried to make a move she kinda clammed up and didn’t seem to reciprocate so i stopped. several times we were hanging out alone in a music practice room drinking (we’re in college) and we just talked a bunch and i would try to make subtle moves to test the water, like sitting closer to her and stuff, and then she would say she was hungry and we would go get food. i figured that meant she wasn’t interested in me but A. we literally met on a dating app and B. she kept asking to hang out afterwards. eventually we just stopped talking after it didn’t go anywhere. i still don’t know if it was just her being weird and indecisive, or if i did something wrong, because i’m fairly introverted and don’t date around a ton.
