Your emotions are all over the place. You want her to read your mind (I even went to bed early without even telling her, hoping that she'd instead ask "what was wrong".) You're passive agressive ("I sat almost utterly silent for the entire weekend.") And you gave her an ultimatum. You are taking much more from the realtionship than you are giving. You need to let her go and figure out why you need so much validation of your relationship and of other's love and commitment, how to have a healthy relationship, learn to communicate, and balance your emotions and reactions.
