its wrong of your girl to do that without asking for your
permission.
But if u two are really close and u have nothing to hide, its
doesnt matter right?
You don't have to shout at her, you said shes your girl, then just
tell her normally and since you dont like it, tell her not to read
your messages as well.
i'm okay when my girl reads my message.
EDIT: eh, pity you now that she shout and screamed @ you in
public..shes in the wrong here..
