Wa alaikum salaam wa rahmatulahi wa barakatuh sister,

 

This is a very painful situation to be in as you see the one you love deviate from the path of Islam. Inevitably this is causing you great distress. Ultimately, as you suspect,  if he denounces Islam then you would no longer be able to be in a marriage with him. It is ok for a Muslim man to.marry a non-Roman,  but not the other way around as you fear may happen in your case.

 

This is because ultimately any children born of the marriage will naturally take the religion of the father, thereof in your case, should Allah bless you with children, they will be drawn to the atheist path of your husband.

 

Unfortunately, it seems your attempts to point the dangers out to him are not working as he continues to bit from the true path. Your most powerful weapon therefore at this point is du’a. Ask Allah to guide him for surely Allah guides who He wills. Make continual prayers to Allah, especially during the times when we are told Allah answers prayers, such as the last third of the night.

 

Additionally, continue to be a good example to him. Take a different approach and instead of pointing out the negatives of what his friend is doing, instead shown him the beauty of Islam so that he is attracted to it once more.

 

Continue to pray and practice Islam openly in front of him and in sha Allah along with your prayers he will see the straight way. If he sees him happy Islam makes you and how it bring out the best in you then he may feel.more encouraged to change and draw closer to the path of Islam.

 

Ultimately, Allah guides who He wills and if after all your efforts and prayers he does not change then be satisfied that you have done all you can to warm him, to guide him and to pray for him and be satisfied that Allah will reward your efforts and good intentions however heartbreaking it is to see him slipping away.

 

May Allah guide him on the straight path and make it easy for you to ensure you current difficulties successfully. May He reward you good intentions towards setting your husband on the straight and true path.
