So i tried to have a relationship with her for two month then I ended it because we where too different.
This feeling of not wanting to be with her because you are too different will happen again if you were to get back with her so continuing to flirt with her to see if she wants to rekindle a relationship with you isn't worth you stalling yourself from getting over her.
You did the right thing breaking it off with her. All you need to do now is accept that fact and let it go.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
