Do you encourage me to return to my country after my faith has weakened due to living abroad, knowing that my absence from my husband might last six months, and he agrees to this despite his strong desires, with the aim of returning to my committed environment, performing Umrah, and completing my studies? And would my staying [abroad] further weaken me?

Emigration from lands of disbelief varies in its ruling depending on people's circumstances. If you fear for your faith by residing there, try to convince your husband to return to your country. If he insists on staying, do not disobey him. You must strive against yourself and resist the whispers of Satan by avoiding the viewing of pornographic sites, seeking help from programs that block harmful websites, fearing Allah the Almighty, dreading His punishment, and occupying yourself with listening to beneficial knowledge and admonitions. Your husband should be an aid to you in this.
