pimps will rely upon the same human frailties as cults do...it starts with the love. affection, and belonging-ness that the woman did not get in her life...look she has friends, friends that will look out for you, then the incremental commitments to acts...so then slowly as the dynamic changes = like the frog in the cold water that is slowly starting to boil - they are in this psychologically controlled situation. Many abused woman (married or similar relationships) find themselves in the same place - and to an outsider, you cannot understand how someone can stick around under those circumstances...but that is how it goes down.
