The short answer is that for most of the women in ISIS, the evidence to date appears to show that they wind up in brutalized, distressing relationships where most of the time they want to get back out of the country when they realize how bad it is.
For a minority, however, including the two young women who I believe are from Manchester in the U.K., they actually rise to senior positions as recruiters where they are capable of recruiting other women from other countries around the world.
So the short answer is that most women who go there wind up brutalized and in horrible conditions and look to get out, but a small proportion of them go on to be leadership figures in the community where they can exercise that influence around the world.
