Agree Sören, about not over thinking things, but in this case is way too late for that.
The worst part is that she continues to say she doesn't know what she wants. Which is bullshit. Id be less angry if I got a fucking definite answer. But Fuck it now.
Let this marinate, this IS her giving you a definitive answer, in her self obsorved manipulative way. Difference is she just wants all options open, because you let her.
For the last time, the sooner you realize I don't give a fuck what she wants anymore, the better off you are.
