As Salaamu Aalaykum

There is a support group for women in polygyny you can read more about it here. The group's website is here

This is a group to support, nurture and provide friendship for Muslim sisters in polygyny. Polygyny is from the Sunnah but it can be easy going and beneficial; or it can be very difficult to come to terms with and a hard slog. This is not a group to degenerate polygyny; but to provide support to sisters whatever their situation. We also welcome sisters who are not considering polygyny for themselves but who want to understand it.
