ruined for marriage
"Now I'll never be a bride..."
Refers to a stock situation where a character (conventionally female) experiences distress, because they have been in some way shamed or made 'impure,' and because of that can no longer get married. The nature of the shame can be anything from being seduced or raped, to being seen in underwear or nude, to simply being caught in some embarrassing act (example: post #1282220).
This tag is appropriate when a character utters an appropriate version of the stock line "Now I can never be married..." The situation is also frequently indicated non-verbally, through one character (the "aggressor") being shown smoking a post-coital cigarette with a satisfied expression on their face, while the other character (the "victim") is crying, most often hiding their face.
