What's your proposing/marriage story?

I'm interested in knowing how fellow Tilders became engaged and subsequently married. Let's just say I was given some personal reasons to think about the subject lately...

I'm interested in knowing what steps led you and your significant other to consider the possibility, how you became engaged, how long did you know each other beforehand, etc...

You know, the kind of thing someone that never considered marriage as an option is utterly ignorant about :P

Any advice?
