I'm sorry but sabr is not everything, she has childen, and her husband is giving her a choice to be patient with him in the way he is right now, that is easy for him, please, there arte some things wich annull the marriage, like leaving prayer, and then comes the issue of the other girls, i don't believe he took pictures and then left, please, a halfnaked girl in front of a man without taqwa, think again...
the sister must think of her imaan, but also about her health, and her honour, you can't ignore this, at least I would''nt.
@ the sister, if this is affecting your imaan or familylife you should think about yourself and your kids, you cant try to guide him to islam while he is pulling you of of it. I say this while having three little kids with my husband, I would leave him immediately for the things your husband is doing, he has no respect. Ghair inshallah. Khula is not loved, but it is an option in some cases ukhti. Ask another scholar, it is easy for a man to say 'have sabr' I see this more often, also on sites like islamqa, but they don't understand what this is doing to you as a wife. How hurtfull and humiliating this really is.
He has no respect for Allah, for you, for your family, he is humiliating himself and you by his actions, and after warning him he is doing it again? He is doing it because he knows you will see it through the fingers, watch out that you don't lose yourself.
