Bad breakup. Old news?

Ran into an ex a few years after a bad breakup. I dropped something off to a friend who works at the same place. Im literally there for 2 minutes and walk out to my car. As Im backing out, I see him looking at me in my review mirror. I drive away. A few seconds later I decided to call him to see if he needed/wanted to talk. He said he was only walking out to his car to find his keys and that he just woke up from a nap and couldnt remember where he put them. Since he own his own business, I told him the place looked nice and that I had a hard time figuring out if I should use the employee door (what I used to use when we dated) or if I should have come in the front (which I did). He then says that our breakup was old news. he appreciate me telling him the place/expansion looked great and that he was just doing the best he could. I told him I had to go. Does any part of this conversation mean anything? Was he happy to see/hear from me? What do men think when they see their exes?
