being ghosted?

I have been talking to a guy everyday for couple weeks. He seemed to be very interested in me because he always the one who initiated the conversation first thing in the morning (he’s more of a morning person so he always wake up early and send a text before I even wake up). Then we went on a 1st date, everything seemed to go very well, he even said it was a good date and we had chemistry. We kissed and made out at the end of the date. But then I forgot to text him that night after he dropped me off. And also the next day since I was so busy with work (I’m not defending myself but monday morning was terrible in the hospital for an intern like me). He texted me in the evening but somehow I feel he was kinda distance so I’m confused. Then the following day he also text me first saying that he’s having a fever and he needs to rest, I reply that I hoped he have enough rest and let me know if there’s anything I could help. But he stopped contact me. I did text him once to see if he’s feeling better and he replied and we talked for a little bit, he told me he was having depression because work is piling up, But after that he never initiate the conversation anymore. Should I reach out to him? Or am I being ghosted and I should move on?
