I think u are very confused. Zero already died long time ago. Yuki kept on for more years like 700 years or so to find a solution to revive Kaname. She revived Kaname by sacrificing herself.
The sequel Memories (the one u are reading on this page) is Kaname finding out what happened during all those years he was “asleep” with Yuki, their daughter and Zero etc.
At present Kaname succeeded in reviving Yuki, they embraced and their confessed their love for each other and died together turning into dust.
Why was she try revive him but not Zero? I heard that in this manga flashback showed her moving on with Zero but it looks like a lie now and also heard that she didn't want to be revived though. Anyway in the end they still made Zero unimportant to her. Like always.
My comment doesn't have it wrong I already concluded Zero died years ago, that doesn't change fact of what I said.
Because Zero died and had his own life who he already lived XD why should he revive someone who already gave everything he wanted to do in life?! Also that’s not true that she didn’t want to be revived. It was simply no other way for her to live and at the same time to have Kaname alive.
So based on two comments. You're telling me Zero is dead and somehow Kaname came back to life then him and yuki died in arms together? Nah that actually pisses me the fuck off. The author is horrible for making Zero alone by himself again even in the afterlife.
Edit: somehow I found the last chapter and base on that fuck ass chapter you're telling me kaname revived yuki and now he's gonna raise her. Boo revive my Zero instead you cunt.
