Extreme mood swings

You admire her for her zest for life and her radiating positivity, but suddenly she is a tearful mess or losing her patience and screaming over obviously trivial matters. Fluctuations in hormones, such as oestrogen, do make some women more prone to mood-swings but if it becomes a problem where she is constantly shifting gears from one extreme to the next or you constantly feel as if you are walking on eggshells out of uncertainty due to her complete unpredictability, you can assure yourself that you are not in a healthy relationship and it would be in your best interest to remove yourself from that environment.
