She didn't talk about it, so I never pushed.

[It's quick and clipped, like a shrug. She's practiced this line.]

I didn't ask her to marry me because I thought our relationship was perfect. I asked because I love her, and she keeps me human, and I couldn't stand not giving her everything I had. If she can't give everything in return, that's fine. She's allowed to keep part of her life to herself. I know I used to.

[And that's how she wound up lying to her boyfriend for months on end until he got hit by a car in the middle of her confession.]
