The fact that we were together for 7 years before we were married, and the experiences that came with that. We were a thing long before I had any money to speak of (or any real financial prospects), and she's supported me through quite a bit as I've supported her. If she's milking me for my money then I have no shame, because she'll have outdone Machiavelli several times over to hide it this well for this long.
Sometimes people actually love each other. I'm lucky in that regard.
