Someone please give some good advice on an ex girlfriend?

ok my ex and i were together for a while, broke up, she was living in florida and i in ohio... she has since moved to cali for 3 months at the minimum... anyhow i broke up with her, we stayed in constant touch, and then she kind of slacked off, i got worried and realized i wanted her back....she wanted to be single. she didnt wnat to give up on us just needed to be single for a while... so anyhow she moved, and she was alwasy contacting me, telling me how happy i am making her, how good i was to her.... i was kind of bieng really nice but not saying anything about liking her or whatever... then last saturday we talked online, had a great convo, and she keeps saying how happy i seem... then after that convo she blocked me on aim, and im still blocked... she hasnt called, and has put stuff on facebook that she knows woudl make me jealous... so my question is. is she trying to make me jealous to get me to contact her? or is she just trying to move on?
