Oyasumi Punpun technically fits your criteria. It's about a boy and the girl he's in love with and spans over a decade.
It's also insanely dark. So tread with caution.
I followed it from the beginning to the end. It's more of a childhood love romance (I don't think they even count as childhood friends, but YMMV) than age progression romance, since they didn't really spend that much time together

Last Gameedit: nvm it's on your reading list. Sorry I didn't check before I posted
Truth be told, I did contemplate putting it up as example there, but forgot to

Spoiler (mouse over to view)

Didint see it in your complete or your reading list so if u havent read it u should try it
Wishlisted it. I stumbled on it a while ago, but the permanent hiatus kinda puts me off.

Hmmm... there are probably tons that fit your description. For example you didn't say how dark/light you want them ? Is slapstick or tragic melodrama a no go ? Does it have to involve teenagers ? etc... If you want some that span over several years then is that to say your main criterium is characte ...
Well anything goes, though I'd say I prefer good ending to bad ending
The first 3 I read like ages ago, probably before I even used mangaupdates. I didn't exactly like the storytelling of Ichigo's author in general though.
Sakamichi feels like shounen-ai most of the time. I was into it for like 20 chapters before dropping, so yeah... :/
I'm about 3 vol into Ciguatera now. Great read
Aku no Hana is okay, I actually didn't like it as much as I think I should. I suppose the cynicism of the story got to me and I direct my negative feelings at the characters.
I will check Planetes after Ciguatera
I already read pretty much everything written by Adachi Mitsuru.
Nah progression can be in the form of either timeskip, or actual plot time. You weren't wrong with your rec

Well I stumbled opon it a while ago. I didn't exactly like both the main guy and girl tbh.
Quote from Blitzkrieglove
Kare Kano
Koe no Katachi (ongoing)
Itazura na Kiss
Yuru Yuri (it isn't really yuri as the name suggests).
It's not like that Darling
Nineteen, Twenty One (Webtoon)
I alrready read Kare Kano. It was good in beginning and middle, but I didn't really like the whole drama out of nowhere at the end.
I've been following Koe no Katachi since before its serialisation

What Yuri Yuri are you referring to? I only see 3 on MU, one is doujin, one is yuri and one is shoujo-ai
Gonna check the last 2 later
