I don't know what has happened between you guise but all just don't see the background and just make girlfriends so what will happen the result is in your front just try to make friend and when you get to know about her that how is she in reallity then increase the level of your friendship to girlfriend. believe me all girls are not bad its only us which make them to behave in a different way so just don't blame girls hat they all are bad ok and trust GOD.
