tldr: Girl I don't know very well said she used to have a crush on me, can't tell if she still does, but if she does, I would definitely like to be more than friends.
So I met this girl in a first aid course, but we didn't talk very much. Turns out we had a common friend, and we ended up hanging out once over the summer before we both went to different universities. We hardly texted, but she ended up telling me that she "used to have the fattest crush" on me in the course we did. She said she thought it was weird because of our mutual friend, and then we sort of became friends, so it kind of seems to me like she doesn't have a crush on me anymore, but we've started talking more. I can't tell if she still likes me or not, and since we're in different places we haven't been able to hang out since.
No idea if this means anything or not, but she seems to take a while to respond to my texts, usually like a week (I respond to her within a couple hours), and there have been a couple of times we've both been home but she ended up being "too busy" for us to actually hang out.
I do like her, and would love for us to hang out more, but she doesn't seem too responsive and I don't want to constantly message her too much with no response, no idea what to do, pls help.
