This is not mine, but it is my favorite piece of writing by Veronica Roth (Writer of the Divergent series)

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. And maybe that's true of beginnings, but it's not true of this now. 
I fell in love with him. 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 I wake up, every day that we fight or lie to each other. I choose him over and over again, and he chooses me.

Sorry, I typed in "every day that I wake up" twice...

I loved this because it is the situation that I am in... I love him... and I stay with him because I love him, not by default. Are there other guys out there? Sure, but I choose him over and over again.
