Guy I was talking to is mad at me for going out with his friend?

I matched with this guy on tinder back in October. We never met up before but we were texting everyday. In April, I matched with this other guy on tinder. When we matched, he gave me his Instagram. When I went on his Instagram to follow him, I saw that the guy who I matched with in October follows him. Not only that, but they're also friends. We would DM each other from time to time. No flirting. Just friendly, normal conversation.

A month ago when the pandemic was still kind of bad, I told the guy who I matched with in October that I wouldn't break quarantine to see a guy until this was all over. Now that NYC has reached phase 2, I have been seeing my friends. The guy who I matched with in April and I made plans to see each other on Thursday but I had an interview for a hospital so we didn't meet up. Right after my interview, I texted the guy who I matched with in October that I had an interview in a hospital because we're both nurses. He left me on read for a couple of hours and didn't reply back to me until a couple of hours later. I texted him and he left me on read and never texted me back since then. It's been 3 days. The other day, I saw that he unliked a few of my pictures and ever since he left me on read, he stopped watching all my stories. Does the guy I matched with in October know that I was supposed to see his friend or is his behavior not related to me making plans to see his friend? What should I do?
