Why do they do this? And how do I tell them I'm not interested in talking, nicely?

They have been distracted by another promising "lead" in their quest to either find a Girlfriend or FB. When that lead plays out or they are told to hit the road, they immediately return to their last, but less promising leads ... while they mine for fresh leads on the side. They are always mining several leads and rating them, giving prime time to the "best" changes they have.
The #1 response that meets your criteria would be
I have a big muscular rich Boyfriend now - he's very jealous and I better close quickly now before he finds out I'm writing this , and gets your name. This keeps you in the game, should you wish to revive it later on.
The #2 response would be to exchange photos (more fun if they send you theirs first), then dig up a photo of the ugliest gal possible to send. If you still have a contact after that, begin asking STD questions - how to cure them.
