I'm running into the issue of women that I'm not terribly into (i.e. I could take it or easily leave it) becoming quite infatuated with me, quite quickly.

How do I tactfully put the brakes on things, either before they get out of hand or when I'm doing damage control?

A lot of what /r/seduction teaches is escallating and I've been accused of leading girls on with no intention of long term relations.
