He doesn't feel that he deserves to be loved, which is why he didn't show himself to sora or kairi until the end of kingdom hearts II.Riku: Stop it, Sora! Don't you recognize me?
Sora: Yeah, I recognize you. I can see exactly what you've become!
(Sora strikes Riku from the top, down. Riku is thrown to the edge of the island.)
Sora: Look at you, shrinking away from the light... You're not Riku anymore... You're just a pawn of the darkness.
(Riku continues to lie on the broken ground.)
Sora: So be it. It's time for you to face the light!
(Light envelops everything. Riku floats in an abyss of light, his existence flickering.)
Riku: I'm...fading... Consumed by the light...
(Riku vanishes into the light.)
Kairi: You won't fade.
(Kairi appears in the white abyss.)
Kairi: You can't fade. No power can defeat you--not the light, not the dark. So don't run from the light--and don't fear the darkness. Both will make you stronger.
Riku: Darkness, too?
Kairi: Especially darkness. Because that power is yours alone. The darkness is your heart is vast and deep, but if you can stare into it unflinching, you'll never know fear again.
Riku: All this time I've been pushing the darkness away...
Kairi: Just be brave. Know that the darkness is there and don't give in. Do that, and you'll gain strength unlike any other. You'll be able to escape the deepest darkness--
Riku: --and I'll be able to see through the brightest light...
Kairi: Follow the darkness, Riku. It'll show you the way to the friends you miss.
Riku: But can I face them...
(Kairi holds her hands together behind her back.)
Kairi: You don't want to?
Riku: You know I do.
(Kairi fades from the abyss of light, replaced by the dark silhouette of Riku.)
Riku: And I will! The darkness--MY darkness--will show me the way!
(Riku returns in his full form.)
Rikku gave himself to the darkness for kairi, I think that he loved her at least as much as sora.
I don't think Riku ever loved Kairi as a GF or anything, but maybe as a sister and got jealous of Sora trying to take her away from him...?...*Sighs*
When riku found sora and kairi rushed to him notice how he left(or wanted to leave)? He knew he wasn't for her: Sora was.she excepted him so even if he thought that she would be shocked he learned that she was fine with him.
