Re: Religion and your spouse
There were prophet's wives who didn't believe (Hazrat Nooh & Luut (as) ) and the Pharaoh's wife is declared to be a righteous woman by Quran. I pondered why didn't they divorce their spouses? Why couldn't they change them to believe?
So what I take from it is that your spouse owe his or her belief to Allah, not you. They will be judged on their own account. I may encourage them to do good (how ever I define it to be) and pray for them but only Allah is the final decider.
I believe that I am responsible for how I treat my wife and with what intentions, regardless of how she treats me in return.
