should I initiate texting my shy coworker? he confesses he has a crush on me!!

a coworker and I were talking about music recs and all of a sudden he confessed that he has a crush on me via a work chat. he says he does not know what to do bc he's never been in a relationship before. he is extremely shy, and the type to get so nervous that he would visibly shake talking to me. I have a crush back and would like to hang out outside of work but bc he said it via work chat i didn't respond so that we wouldnt get in trouble. when we came back to the virtual office, we were both nervous on our video work calls. finally the chat that he shared disappeared within 24 hrs, so technically speaking I didn't respond back to his confession. I messaged him at the end of that work day and said "excited to share some music recommendations tomorrow!" to make him feel less nervous. the next day, we were trying to be smooth and I set up a door of opportunity for him to ask me for his number. I got his number and texted him after work (to set up boundaries that we should keep work time for work and play time for after work). he responded fast and it was a normal conversation but we just got tired from the work day so he left my text hanging because he prob fell asleep. he hasn't initiated a text for a day and a half. should I initiate a text or shpuld he since he is the last person to text? I really would like him to ask me to hang out and feel comfortable texting me, but I feel like I put him in a weird spot because I technically did not respond to his confession with words, but with action that may not be as clear.
