Ex wanting friendship or more you tell me??

My ex had affair and then 2 months after I found out he dumped her and she then finally 4 mths later filed for divorce but during all this time she wants to be friends, so anyway she wouldn't communicate w/me while I tried to keep us together she had a 1 track mind and w/help from her stepmom she divorced me. 3 months later the dissilusion was final she left me most everything? So, she then asks me after I finally talked to her 5 months later if ( I was over her ) ? whats up with that first of all? then 2 weeks later her son worked on her car here (he lives here) but before I didn't let it happen so I helped him on the car on some things cause he is not very complete w/his work. Then she ask me if I was making stepping stones to get back w/her ( probably cause I left her a message on the phone that she needs to address some things on her car ) ? I thought this is my time to see what she wants and so I asked her the same she asked me weeks ago ( are you over me ) ? She didn't want to go there ? and I said you asked me and I answered so it's your turn so she said yes she was over me. then I told her all the things she said and did before and after the divorce made me think I was on a roller coaster, and she said nothing so I said that I now know where I stand and take care and good luck she then said can we be friends and communicate ? so I said I know where I stand good bye. What do you think she really wants from me the kid is 21 and doesn't need us like an 8 year old so what is up???
