I accidentally blocked a guy in my class from friendship and now I want to die

Throwaway bc this is kinda embarrassing<br><br>I've (22f) had a crush on this guy (23m) in my class for a while now. I never told him, but I would talk to him every now and then and I thought he was nice enough.<br><br>We were on a group project and we had to do a group chat together. The other two people were really giddy and in love with each other and left us alone in the chat to plan everything together. We messaged each other for a while, and at some point I asked how he felt about girls in short pants (I wear shorts a lot) and he said he wasn't into them. That stung a little. <br><br>Then I kind of forgot about it all and we ended up doing well in our project.<br><br>Later, the same guy asked me to study together, and we did. He asked me out of the blue if I had a boyfriend, I said no and he asked if he could kiss me. I said no because I wasn't into him anymore after what he said earlier. He said okay and we kept studying. <br><br>I feel so stupid and I want to die bc if I had just kept my big mouth closed and not asked him if he liked girls in short pants, I would have known I liked him and I would have said yes, or at least not rejected him so harshly. Now I feel so ashamed that I ruined my chance at liking him just bc I couldn't shut my mouth.<br><br>I'm so stupid, I really want to die
