Can someone please help me translate this line from a manga I'm reading?


> お前だってもうずっと俺以外の血を望まなかった

I'm basically torn between two interpretations:

  1. You haven't wanted any one's blood but mine for a while now
  2. You've never wanted any one's blood but mine




(もう)ずっと～しない / (もう)ずっと～していない means "have not done ～ for a while." So this
sentence means 1. That is, this person(?) wanted (and probably actually
enjoyed) someone else's blood a long time ago, but it's been long since he did
so last.

> もうずっと彼に会っていない。  
>  I haven't seen him for a long time.
