"She was a soul-sucking bitch anyway!"-Ex-husband
"He was such an asshole!"-Ex-girlfriend
Your ex, shrew, she-devil, bastard, asshole, in social relationships, an ex (plural is exes) is someone with whom a person was once "associated" with as opposed to being responsible for as a burdening thing of the past.
As a prefix, ex- can refer to a variety of different relationships and usually with gender roles.
Here is an example one might say that my ex-girlfriend was such a baby and "I never wanna see your ugly face again to her face" both ways that phrase means the same thing.on the other hand, the ex-wife or ex-girlfriend has no room into your life, therefore, you don't want her.
Your Ex-Wife, Husband, Boyfriend or Girlfriend
Your ex is an egotistical and manipulative jerk or shrew that has done you wrong and therefore you never want to see him or her again.
Sometimes you are the problem not them and therefore you demonize them for your mistakes which is a total shitty thing to do since you broke up with them vice versa.
