Why did my ex do this?

so my ex broke up with me almost three months ago. about a week ago she send me an accidental text message. a week later she tells me Friend that if i want to talk to her to go ahead and do it.so i text her and she text back. we talk things to get awkward. anyways. i tell her about the accidental message and she tells me she was trying her new phone out. we end the convoy. later i find out that my friend send her an email of things i told him. i send my ex an email. and tell her that my friend told me that he send her an email the same day she text me. and tell her that if she wanted to talk we can but we can start by emailing because it was kind of awkward. anyways. the next day she gos into the joint account on myspace deletes all the pics of us and types in the status moving on.why go threw all the trouble to talk to me then do this?
