I've been in a romance mood lately and I'd like some recommendations. Not just any kind of romance, though, I want romance anime that'll make me cry. I want the best (and saddest) recommendations you have. Both series and films are fine. Do your worst! :)
The girl who lept through time is low key heartbreaking (though romance isn't the only part of it). It's one that always got me very emotional, and the ending really guts you.
The old school (very old school, 20yrs old for some of these now) Kyoto Animation eroge adaptations (Air, Kanon, Clannad) all had a lot of melancholy, though they're all blurred together in my memory and I can't remember which was the real tearjerker.
Perhaps not as tragic, but melancholic to the core is Whisper of the Heart, a really good Ghibli film that foregrounds the romance.
Like @Cromalin@hexbear.net , I also have to every time emphasize Gunbuster and Diebuster. They're mecha anime, but focused on the characters and like utena, the main relationships (especially in Diebuster) make me cry every time.
This was very helpful, thank you!!
