Narrative:

Upon flying from ZZZ1 to ZZZ2 with a passenger, I inadvertently strayed into class B airspace while my passenger and I were looking at sights on the ground. I then noticed that ZZZ3 was off my left wing and that I was at 5500 ft. As my heart sank, I decided that I should do the same, so I turned right and descended to 2500 ft to exit ZZZ3 airspace. I leveled off at 2500 ft and continued to ZZZ2 airport. As I passed ZZZ airport, I monitored the control tower frequency and heard them talking to another aircraft. ZZZ3 was asking the other aircraft (a cessna) if they had seen another unidented aircraft in their area. He said he had, but couldn't identify it. ZZZ3 tower told them not to bother pursuing further, but the other aircraft decided to chase after me anyway. He got to within 100 yards off to the right of me. I did not see him, but my passenger did. He reported my number to ZZZ3 tower then turned left and passed over my head by less than 200 ft. It was then that I saw the cessna aircraft. I continued to ZZZ2, dropped off my passenger, and continued on to my airport.
