guy crush? At his workplace

Hey so for the last couple months I was really struggling with myself and my self esteem so I’ve been trying to take myself out on solo dates and I’ve been going to all different kinds of restaurants and managed to go to this Chinese restaurant the first time. I’m not sure if I was crazy or what not but there was a waiter who had peaked an interest in me (as in he would serve me and till me every single time even though there were other waiters that could’ve served me as well, (keep in mind while I was eating there the other waiters seemed like they knew somewhat that he had an interest in me bc they kept giggling and teasing him after everytime he served me, I could make out what 80% of what they were saying bc I also am a native Chinese speaker) there were a few moments where we would lock eye contact and time would slow down which made me feel we had a connection. I liked the food they served me so I began going there a bit more often (surprise surprise, that same waiter would end up serving my food and tilling me, but then he offered a discount to me the next time I ate) the next time I came in to the restaurant I decided I’d give him my number. I had my friend come along with me but he looked a bit nervous, anxious even. I ordered my food and it was time to pay my bill so I wrote my number down on a napkin and handed it to him.
He took my number with a shy smile and I left the restaurant
After a couple hours (I’m assuming a couple hours right after his shift) he had texted me and I was so excited. I thought that I was stepping in a completely new direction in my life bc I just gave my number to some waiter who seemed like he liked me and I was kinda interested in him. We exchanged instagram handles however the texts have been rather disappointing . There would be times where I would respond him back about himself but he’d leave me in delivered for a long time but he’ll still view my stories.
Although he was just a waiter I’m not sure if he was just genuinely a busy person or he simply had no interest in me at all.
What should I do. Should I wait for his response? Reach out again? Or just move on because I genuinely thought that maybe we had a connection
