This makes me want to read the book!

I've actually read a book that has a similar premise but it's not apocalyptic despite there being zombies--but it was very long ago that I read it. The main girl character actually falls in love with a zombie and he seems to love her but it's for actually much more political reasons...

I don't remember it being a great read, but it was okay. And I think it was set up so there would be a sequel. (I'll have to check that out.)

The book was Generation Dead by Daniel Waters.
