Guys, Help Me Out

I met someone while I was on my way home from the office. I wasn't in the mood for anything just focused on getting home. However, as I passed through the market, I spotted a girl who caught my attention. I thought about talking to her, so I parked my vehicle and approached her. She was adorable, wearing glasses, and her smile was just cute. We struck up a conversation, and I complimented her. Then I suggested we go for some momo, and to my surprise, she said yes! I was overwhelmed and a bit nervous by her response, and then we went for Momo and talked so much about everything. She is a cabin crew, so she was telling me about her work and everything. I was just listening.

After that, we went for a coffee, and we just talked about everything, from movies to life. She was telling me why she watched Harry Potter all the parts 9 times in a week, and I was so fkn nervous. I was like, still processing the whole situation. Then we had coffee, and after that, We were waiting for her friend to come. Then we went back to the place where we met. and it got late. Then my dad called me, and I had to leave. Also, she had a flight the next day. So, we decided that when she comes back, we’ll go watch a movie together. Then we hugged, exchanged Instagram id, and left. (We were together for like 3 hours.)

But after that, I texted her, and she’s just replying dry or just ignoring idk why. Like one-word replies. Help me, guys, what to do here? i really don't want to mess this up:)))))
