I looking for Love Triangle where both the guy and the girl like each other but the guy for some reason or another has to prioritize another girl which make the main love inters jealous and insecure ,manga or anime is ok with me.
Examples:

- Aishiteruze Baby: Kippei & Kokoro were dating at time where he has to put Yuzuyu ahead of kokoro which made her insecure.

- Full metal panic: in one episode of the anime that Sousuke choose Tessa over Kaname when they were taken hostage which hurt her feeling even though he likes her but his duty to make sure that Tessa is safe.

-eureka seven: Holland pays so much attention to eureka, which make Talho very jealous toward the way he treated Eureka.

I don't want: hentai, shoujo ai/yuri, shounen ai/yeoi, lolico.

crazy for you

Koi, Hirari
The situation is reversed a little in Koko ni Iru Yo! in that
I guess if you want a kind of twisted take on it, you can watch School Days (the anime, not the manga).
That's all I can think of right now, but I hope these match what you're looking for.
