Anime with actual relationships.

I love romance anime, or any genre that also has romance involved, but the vast majority just tease the "will they / won't they" for 12 to 24 episodes then it's over. Or a couple gets together and none of the progress or relationship is shown.

I want some recommendations that actually flesh out a couples relationship like A sign of affection or Say I love you or Lovely Complex.

The genre itself doesn't matter, I just want to see more about relationships than being blue balled into reading the Manga to potentially see a relationship.
