Mangas with female leads with big moe eyes? Or as my boyfriend calls them bug eyed freaks? LOL I love them they're so cute 😳 😳

Do you mean like in old shoujo? They have lots of those style-wise.

For example:
Kamichama Karin
Gokkun! Pucho

Kirarin Revolution

It might be good to provide a reference picture lol
But if you look at manga from the early 2000 like before 2010 that art was very very relevant to huge bug eyes

Also maybe look into these artist
ANDOU Natsumi
SAKAI Mayu
ENOMOTO Chizuru
TAKEUCHI Kozue
OOUCHI Natsumi
TANEMURA Arina
MAITA Nao
FUJIWARA Yuka
TOOYAMA Ema
ICHIKAWA Shou
TAKAMIYA Satoru
AMANE Yuko
YAMADA Daisy

Most of their female characters have eyes that take up legit half of the face.

Nice reference! I know some of them and yeah oldies have that kind of look lol

You still find it nowadays on shoujo kids manga tho. I recommend Yabuchi Yuu's works but maybe it's too girly for your taste.
