Sudden shift in him lately?

I’ve been seeing a guy since December. We knew each other from college and reconnected by chance. We’re both going through divorce/separation, we bonded over that and it turned into more. There was an attraction years ago and it hadn’t gone away. The beginning was super passionate, constantly texting, great convos, couldn’t get enough of each other. He was the one pushing to be an “us,” said he messed up years ago and hoped he could make up for it now. We also were both changing jobs and moving to a new city. Everything was going great, obviously Covid19 hit and mixed things up, we both ended up back in our hometowns at our parents homes, which are still close to each other. Despite that we still found ways to see each other. About a month ago I started to notice a little switch in him, less enthusiasm, our texting changed, when we’d see each other he wouldn’t be hands on where he used to not be able to keep his hands off me. I did finally say I noticed he was off, he attributed it to the weird time we’re living in. We’ve always been super honest with each other so I let it go at that. But I’m still getting the same vibe, possibly worse since our sex life has also changed. I can’t help but take it personally, I don’t know what happened to cause this shift. I know I need to come right out and ask him, but I fear the answer now that I have real feelings for him. Just wanted an outsiders take on what might be happening.
