Should I apologize for ghosting someone?

a few weeks ago I received a message from a guy I was seeing saying that he misses me. I only liked him as a friend and I didn‘t know what to reply but eventually I forgot to text him back. I feel sooo bad about it but now time has passed and I don‘t know what to do or say, should I text him and apologize or just leave it at that? I don‘t have feelings for him or miss him or anything, I just feel so bad about just ghosting him though, I know it was not very nice or good. what would you do?
