Help with ex issues?

my ex wife who had affair wants to be friends/civil after our divorce was final. she took 6 mths to file first of all and if you really want a divorce why take so long to file and kept saying things that would give me false hope as tho she was still going to be there for me. I asked her if we got back together what would she do with her trailer and she said her brother would stay there with a fast response. she filed for divorce and knew how much I still cared for her even after her affair. so basically my question is does she still want me or what? I think her evil stepmom had talked to her and got in her head. I also asked her if we ever got back together who in her family would be upset and she said probably just the stepmom. she has called 6 times since dec. 10 when we got the divorce if you file for divorce isn't the last person you want to talk to is your ex?
