Book recommendations: Dystopian romance (human/human)

I’ve read through several posts and comments and I can’t find what i’m looking for.

My favourite genre is YA dystopian fiction, i’ve read several that include some romance, but as they are YA fiction, there’s no spice like I want.

Wants: - human/human only - no non-human characters - government control - civil unrest - post-apocalyptic (as long as it’s all human)

Looking for characters/books similar to these: - Tris & Four (Divergent) - Clarke & Bellamy (The 100) - Katniss & Peeta (Hunger Games) - Thomas & Teresa (Maze Runner)

Looking for something similar to the above book couples but more romance. If you’ve read these books, what adult books come to mind with similar story lines and relationships?
