SO, there's this really cute girl at my uni, and we met at the begining of the semestre, we share some clases so we started hanging out once or teice a week, after a bit, I asked her out to an open mic night, it started kinda late on a Friday, so she said yes at first but later told me she was tired, so nothing happened. After a couple of weeks, I tried again, this time to a gastronomical festival in our town, and she also said yes at first but later turned it down under the excuse that she had to do homework. This was about a month ago, we still hang out during lunch break a couple of times a week, we talk and she even laughs at what I say sometimes. Am I making her feel uncomftable?, Is she just rrying not to be rude to me? Im really unsure, becuase both times I asked her out her excuses were perfectly valid, but I still felt she just didn't feel like it. I haven't tried asking her out since then (obviously). What should I do? Any signs I should recognize?
