Is the guy no longer interested in me?

I met this guy on Hinge. We went out twice , the way he talked to me in person or in text really felt as if the guy is interested in me but after the 2nd date , I could sense an energy shift from his side, he is not available anymore like he was between the 1st and 2nd date (The second date was 3 days after the 1st date ) Though he had mentioned he has a hectic work schedule so I gave him a benefit of doubt that maybe he is busy and even tried talking to him about this but he said I am overthiking and I shouldn't worry about it but still I feel he is just keeping me hanging, I don't know I am just very confused.

Is the guy no longer interested in me?
