Recently broken up with a long term girlfriend, ended things on fairly good terms. 
A couple of days after I go to visit a female friend of mine (I’m a straight guy if it matters) and we spend 3 or so hours walking her dog around the town where she lives. 
Later that day ex-girlfriend gets wind of it and all hell breaks loose, claiming I’ve moved on too quickly even though it is a friendship with this girl and nothing more. Ex girlfriend ensures everyone at our workplace finds out by crying in front of them, making me look like the asshole.
Am I?
