My phone accidentally dialed my ex's number.

My phone accidentally called my ex boyfriend number this morning. It was in my bag but I guess somehow the keypad get unlock and dialed his number out of my address book. I haven't called him for more than 9months. We still work together sometimes. Anyway, I check the called history and saw that he answered my called for about 4minutes. That time I was just walking from home to the bus stop to work. Why would he answered for 4minutes? Does he still likes me? I mean if its me, I would keep listening to the background noise if I like that person just to see what he's up to. What do you guys think?
