Trying to restart convo with guy but delays in responses

I started dating a guy a month before coronavirus started. He got coronavirus and we stopped talking as much. It was also impossible to see him without incurring risks because we live pretty far apart from each other. I called it out and said let's pause dating, and he said he was having a hard time dealing with quarantine and said let's catch up when it's all over.

Fast forward 3 months, I realize corona won't be over for a while but restrictions are being lifted now. I also moved and now live closer to the guy where meeting up is now possible. I ask if he wants to catch up on a walk, but he responds to be 3 days later saying he would like to but he's actually back in his home country and that he was flying when I sent the message. I am assuming he's going to be in his home country for a while because it is requiring visitors, including citizens, to quarantine for two weeks. I tell him I live in the same borough now and let's catch up when he's back. He responds again, a few days later, and says perfect and asks me how's the city like. And to be clear, I do believe he's actually in a different country because some of his responses have been at like 5am.

I can't tell if he's already lost interest or his responses are sparse because he's out of the country and possibly busy with mandatory quarantining or preoccupied with his trip. At the same time, I'm also spacing out my responses because I'm mirroring his response time and also he's on a trip and I don't want to come off as needy. Why would a guy use words like "would like to" and say "perfect" if he didn't really mean it? Why say "let's catch up when it's all over" if he didn't mean it? Am I overthinking?

I totally get that we were only dating for a month, and it was very much still trying to become something. I'm not putting all my eggs in one basket, but I did like what I had with him, we were seeing each other multiple times a week, and it would be nice to see if it can still go somewhere despite coronavirus putting a wedge in it.
