Does she like me? Confused.

Met this girl in school (grad). Been hanging out for several times over two weeks - really long sessions with sports, shopping, food, going to each other's dorms. Nothing explicitly intimate happened, but there were moments (sitting close, her ears turning red when we touched, inviting me to her room after mentioning her date). Had deep conversations, she laughed at all my jokes. Started to feel she might have feelings too - she kept extending our time together, seemed to create opportunities for something to happen. But I never had the guts to make it explicit or call anything a "date." Few days ago during a multi-hour hangout where she seemed to be giving me chances (kept finding reasons to extend our time, physical closeness), she casually mentioned she had a date that night. Later told me it went well and showed me her dating app with dozens of matches. Mixed signals? Close-friend-zoned? My own blindness? Cultural confusion about American dating? Still processing.
