Why is he curious about me after a year?

I was talking with him for 2 months and we went out once. Then he said he didn’t want to continue because if ”different life goals”. I said fine and went in to no contact immediately. This happened last year. We’ve been in no contact for almost a year now.

In January I bumbed into him in public and he was staring me until I walked past him.

Recently he viewed my instgram story and he doesn’t even follow (my page is public)

Is he sending me hints or something?
