My ex boyfriend broke up with me 10 months ago. Last week we accidentally ran into each other in the street. He walked me home, however he was headed to the opposite direction. We laughed a lot, he even stroke my cheek, he wanted to have a bite from his chocolate, and when we said goodbye, he looked back as well. I don't want to read too much into it, but I think it was more than what was needed to be polite. What do you think about his behavior?
