Is this weird? Or what does this mean?

I go on the same bus as my ex's little sister and she still has my keychain I bought her on summer vacation a year ago. I can't stop thinking about it. Me and ex mutually decided to break it off and to be good friends but unfriended me on everything. So really I don't know what to think about this whole situation. (￣∇￣")

Someone help and answer.
