Ex girlfriend broke up with me but..?

[giganticgun464]

she doesn't want me to remove her from all social networking sites. She says it would make her feel awkward, so when I try to talk to her on them it's like pulling teeth/making conversation with an armadillo.. it's very short responses, like she's angry with me.

But when I told her I was moving on (I used the wrong term), her responses were rapid and more detailed, it was like she wanted to talk to me. She even said goodnight..

lots has happened since then and she told me she wants our conversations to be like that, but I feel that was just a fluke.

why was it like pulling teeth?
why were her responses rapid?
why does she want our conversations to be like that?
