An ex girlfriend is a female who you used to be romantically involved with, and then the relationship broke apart. This can happen for many different reasons. Sometimes an ex girlfriend is still considered a friend, but far too often the relationship ended on bad terms and this female now views you as an enemy or someone that they want to forget.
Just remember that when nobody was there for you, I was. And when nobody else gave a damn, I did.
Stop asking me to trust you while I'm still coughing up water from the last time you let me drown.
Walk away from people who put you down. Walk away from fights that will never be resolved.
