Somehow I got involved in a conversation about when a person knows they
want to marry the person they are seeing/with/dating/etc. I've never
been married and do not currently plan on it so I don't know. I thought
the question was interesting though.

So for all you married (or single) folks out there. My question is when
did you know the person you married was the person you where gonna marry?

So far I've heard people say that they knew on the first date all the
way to several years after dating.
