I think no one can tell you what to do.
you shuld do what yo ufeel to do, you and only you know all the situation around you adn your girl. Consider many factors, why she did, can happen again? and so on.
what i mean is you shuld look insid eyou and make a decision, i don't think we can tell you what to do.
