I think the quote below is a pretty amazing take on love, especially for a YA book. No offense to Roth or the YA genre, but generally you get an obsessive or lustful love...this statement tells it like it is. Love is work sometimes.
"I used to think that when people fell in love, they just landed where they landed, and they had no choice in the matter afterward...
...But I don't just stay with him by default as if there's no one else available to me. I stay with him because I choose to, every day that I wake up, every day that we fight or lie to each other or disappoint each other. I chose him over and over again, and he chooses me."
Allegiant, by Veronica Roth
