Is a woman considered to be at fault if she desires to live with her husband to preserve her chastity physically and psychologically, and is she entitled to seek a divorce if he does not respond to her desire, especially after it was agreed before marriage that they would live together?

You are not wrong in wanting to reside with your husband, for the gathering of spouses encompasses many benefits. A husband should not be absent from his wife without a compelling need. It is the wife's right upon her husband that he not be absent from her for more than six months without an excuse. It is advisable to communicate with your husband to reside with him in a place where you can be together, and where both your religious and worldly affairs are safe.
