She Liked me so much and looks like she's not interested anymore?

So there was this new Girl [26 F] I 24[M] saw, she comes in my hobby group. she's extremely pretty and sweet. I went out and talked to her, took her number. Seems like she likes me too !!

We text daily , She even replies to all my status and wants to be with me.( Always around Me, ignores other boys). She even puts out statuses exclusively for me.

Our group went on a trip and she went out of her way to be with me, she held my hand and stuff . Was with me 24/7, Even started caring for me. She even took the lead and asked me out on a date.

On the date , She was happy , she was her usual self . After the date She texted me that she was grateful for me.

We planned to go to another place the next day. Unfortunately the place was closed and I suggested we go elsewhere. She said we'll go some other day as she's tired.

And then boom. Nothing. Not replying to my texts anymore ( before she was the one texting me) idk what's wrong .

What should I do? I kinda like her and I'm sad she's not replying for no reason despite being the one to like me before.
