Honestly, it's far from plotting because you don't start off in the first conversation what your demands are and not every date means marriage. To start a discussion about marriage, there must be a connection and knowledge about each other from between both parties. That is at least how I see it.
Wow, so this dating thingy, is it between perfect strangers?
So you don't compile a case file on the assailant (I mean person) beforehand nor heavy vetting. What about rapport building?
