Let me first commend you for choosing to revert to Islam. I pray to Allah to help you remain steadfast and bless you in your efforts to do so.

 

Now that Allah has guided you to the straight path and opened your hearts to follow the truth, it is advisable that you stop living with the man without marriage.  If he chooses to believe in God and His revelations, then you may marry him and continue living with him.

 

Otherwise, it is clearly wrong. I pray to Allah to inspire you to make the right decision.

 

I know such a decision can be hard on you. However, you may do well to recognize the fact that God is in charge of all the affairs of the universe including your life and mine. He reminds us in the Qur’an that God always open doors for us when we choose to turn to Him: “Whoever is mindful of God, He will provide for him (or her) a way out of troubles.” (At-Talaq 65: 2); and “Whoever is conscious of God, He will provide him (or her) comfort and ease in all of their  concerns.”  (At-Talaq 65:4).

 

I pray to Allah to shower you with His mercy and grace.
