I confessed to a guy and he didn't reply. What does that mean?

Hello guys!
There's this guy I met online (Nov. 2019) We talked via text and we clicked and jived. We have been texting for a week. After that, he asked if we could meet up but I instantly told him I have a boyfriend. He said it's okay, he's willing to be friends and he still wants us to see each other physically. I declined and said we could just email because my boyfriend might see it. He agreed. No, we aren't flirting. It was just casual talk. Our email become more rare as finals week became nearer. During my finals week (2nd week of December), I finally decided to block him, and I didn't respond to his emails.
Last April 2020, I checked and saw that he emai-led again asking how I was. I replied and we talked occassionally (again, not everyday). During my finals week for that semester), I didn't reply to his emails again. I emailed him 2 days ago and he told me to just "email him whenever I'm free". by the way, he wasn't mad that I just disappear out of the blue, I guess he understands. Just yesterday, I confessed that I like him, for peace of mind. I said sorry for ignoring him because I have a boyfriend and that I hope we can still be friends. He hasn't replied ever since. What does that mean?
Thank you so much for those who will answer!
